gaya

My code is not working. Please help me by giving some sample code to restrict the digit in the textbox with backspace working.Otherwise please tell me what else the changes to be made in the above code.

The following is my code.

function noAlphabets(evt,val) {var no=val;		  var charCode = (evt.which) ? evt.which : event.keyCode;		   if (charCode != 46 && charCode!=8 && charCode > 31  && (charCode < 48 || charCode > 57 )  )    {			 return false;    }else{if ((/^[1-4]/.test (val))) {//alert ("No should be within 1 character");return false;}}}<td>correct Answer<font color="red">*</font></td><td>:</td>   <td><input type="text" name="corr_ans" id="corr_ans"  size="16" onkeypress="return noAlphabets(event, this.value)"></td>

the backspace key is not working.Please anyone help me. I dont know what i'm doing wrong here.

Hi, My form is having fields like year, pageno,chapterno,standard and correct answer. I have written the script

function isNumberKey(evt , val)	   {    var no=val;		  var charCode = (evt.which) ? evt.which : event.keyCode;		   if (charCode != 46 && charCode!=8 && charCode > 31  && (charCode < 48 || charCode > 57 )  )    {			 return false;    }   else    {	 if (no.length < 4)	 {	 return true;	 }    else if(no.length ==4)	 {	 alert("No should be within 4 characters");	 return false;	 }    else	 {	 return false;	 }    }		  return true;	   }

But for correct answer i need to restrict input to one of the digits 1, 2 ,3 or 4. please tell me how to do this with another function.

I'm doing a code for creating question bank for all subjects. I've dont the coding for 6different question type,like fillup,choose etc.In future, if any more new question type is added by admin,the page should not be viewed empty. Just it should show an imge like page is under construction.so i'm trying to create a empty php file and the img code sholud be written in that php file using fopen() & fwrite(). This is what i'm trying to do.

Thanks RezaRohani. It also works. But in the above code what i posted i simply close the </table> before pageno and opened a new <table>.

<form accept-charset="utf-8" action="a.php" method="post" name="choose" enctype="multipart/form-data" onSubmit="return validate();"><table align="center" border="1" width="850" height="500" bgcolor="FFF5EE" ><tr><td><table align="center" bgcolor="">  <tr><td align="center" colspan="10"><img src="img/laugh.gif" alt="Smiley" /></td></tr>  <tr><td align="center" style="color:#FF0000; text-decoration:blink;" colspan="10" ><b><?php echo $qtype2;?></b></td></tr>  <tr><td colspan="10"> </td></tr>   <tr>   <td>   Question<font color="red">*</font>   </td>   <td>   :   </td>     <td><textarea name="ques1" id="ques1" cols="25" rows="5" style="resize:none;"></textarea>   </td>   <td>	<table>	<tr>	<td width="10">	<div style="background-image:url(img/mic1_30.jpg); width:30px; height:25px;" >	<input type="file" id="quest_wav1" name="quest_wav1"  style="opacity:0;-moz-opacity:0 ;filter:alpha(opacity: 0);" size="1"  />	</div>	</td>	</tr>	<tr>	<td width="10">	<div style="background-image:url(img/img1.jpeg); width:30px; height:30px;" >	<input type="file" id="quest_img1" name="quest_img1"  style="opacity:0;-moz-opacity:0 ;filter:alpha(opacity: 0);" size="1"   />	</div>	</td>	</tr>	</table>   </td>   <td> </td>    </tr>  <tr>   <td>Page No<font color="red">*</font></td><td>:</td>   <td><input type="text" name="pno" id="pno"  size="16" onkeypress="return isNumberKey(event, this.value)"/></td>   <td> </td>   <td> </td>   <td>Chapter No<font color="red">*</font></td><td>:</td>   <td><input type="text" name="cno" id="cno" size="16"  onkeypress="return isNumberKey(event, this.value)"/></td>   <td> </td>   <td> </td>  </tr>  <tr>   <td>Board</td><td>:</td>   <td><input type="text" name="board_txt" id="board_txt" size="16" readonly="" value="<?php echo $boardname; ?>" style="background-color:#FFFFFF;" /></td>   <td> </td>   <td> </td>   <td>Subject</td><td>:</td>   <td><input type="text" name="subject_txt" id="subject_txt" size="16" readonly="" value="<?php echo $subjectname; ?>" style="background-color:#FFFFFF;" />     <input type="hidden" name="language" id="language" value="<?php echo $language_name; ?>" />   <input type="hidden" name="qtype" id="qtype" value="<?php echo $qtype2; ?>" />   </td>   <td> </td>   <td> </td>  </tr>  <tr>   <td>Short Type</td>   <td>:</td>   <td>   <select id="short_type" name="short_type" >   <option value="" selected="selected">----</option>   <option value="Problem" >Problem</option>   <option value="Deleted">Deleted</option>     </select>   </td>   <td> </td>   <td> </td>    </tr>  <tr><td colspan="10">  </td></tr>  <tr>	  <td><font color="#FF0000"><b>Note :</b></font></td>	 <td colspan="2" align="center"><font color="#FF0000">*</font> Mandatory Fields</td>	 <td colspan="3" align="left"><img src="img/mic1_30.jpg" alt="Upload Wave" />Upload WAVE</td>	<td colspan="4" align="left"><img src="img/img1.jpeg" alt="Upload Image" />Upload IMAGE</td>  </tr>  <tr>  <tr><td colspan="10">  </td></tr>   <td colspan="10" align="center">   <input type="submit" name="add" value="Add" style="background-color:#FFFF00; font:Arial, Helvetica, sans-serif; color:#FF0000"/>	   <input type="reset" name="clear" value="Clear" style="background-color:#FFFF00; font:Arial, Helvetica, sans-serif; color:#FF0000"  />   </td>  </tr> </table></td></tr></table></form>

The above is my formWhat What i want to do is i need to equalise the fields.As the question field nearby is empty space. But the other subject is in right side and board in left side.But no fields is seen nearby question field. Simply i want to fill the space.

In the first mentioned code i simply use the if condition alone. Where i'm creating a new type,i included the code as

 $qtname1="$qtname";	   $var1=fopen("$qtname1".".php","x+");$stringData = "<img src='../uc1.jpg'/>";fwrite($var1, $stringData);fclose($var1);

In the above code $qtname is the name what i am entering newly to the database,and open the created file name included image using file write. ie)$qtname=a.php.

Is it possible to change the width and height of textarea.If means please tell me how to do that.The following is my code.

<tr>		    <td>		    Ques:<font color="red">*</font>		   		    </td>		   		    <td><textarea name="ques1" id="ques1" cols="25" rows="5" style="resize:none;"></textarea>		    </td>		    <td>			    <table>			    <tr>			    <td width="10">			    <div style="background-image:url(img/mic1_30.jpg); width:30px; height:25px;" >			    <input type="file" id="quest_wav1" name="quest_wav1"  style="opacity:0;-moz-opacity:0 ;filter:alpha(opacity: 0);" size="1"  />			    </div>			    </td>			    </tr>			    <tr>			    <td width="10">			    <div style="background-image:url(img/img1.jpeg); width:30px; height:30px;" >			    <input type="file" id="quest_img1" name="quest_img1"  style="opacity:0;-moz-opacity:0 ;filter:alpha(opacity: 0);" size="1"   />			    </div>			    </td>			    </tr>			    </table>		    </td>		    <td> </td>		   	    </tr>	    <tr>		    <td>Pno<font color="red">*</font></td><td>:</td>		    <td><input type="text" name="pno" id="pno"  size="16" onkeypress="return isNumberKey(event, this.value)"/></td>		    <td>Cno<font color="red">*</font></td><td>:</td>		    <td><input type="text" name="cno" id="cno" size="16"  onkeypress="return isNumberKey(event, this.value)"/></td>		    </tr> 

Please tell me i've to increase the size of textarea for the question field only. Please tell me how to do that.

Ya i just want to create a new empty php file like "empty.php". I did it. Now i'm trying to do,by creating that php file, i am trying to show some image.Is that possible.please tell me

sorry Deirdre's Dad. Sorry for giving such a wrong advice. But some of the code won't work in some case. That time i include that config.php file. Thats why i replied like that. Extremely sorry for giving wrong advice.

The fopen() is for creating an empty php file.

for($i=0; $i<6;$i++){if($var[$i]==$str){echo "$str".$var[$i];$strfirstlettercaps = strtolower($str);$var1=$strfirstlettercaps.".php";require_once $var1; }else{$strfirstlettercaps="";$var1=fopen("$strfirstlettercaps".".php","x+");echo "<img src='../uc1.jpg'>";} 

The loop is checking for both if and else condition. I dont know why.please anyone tell me what i'm doing wrong here.

I did it.Thanks justsomeguy.

Thanks justsomeguy. I used the following code and compared the two values.

for($i=0; $i<6;$i++){if($var[$i]==$str){    echo "welcome----".$str;	    $a=a.php;[/font]} 

Now i have to include another php file inside the if condition,storing the php file name in a variable like $a=a.php,and when clicking it have to open the corresponding output in which a.php file is needed. Any ideas please tell me.

I found out the solution for this

$sql="select type from qtype";$result=mysql_query($sql);$var = array();while ($rw = mysql_fetch_array($result)) {  $var[] = $rw['type'];}print_r ($var);

But now i have to compare the two fields.

$quer="select type from qtype whereid='$qtype'";$res=mysql_query($quer);if(mysql_num_rows($res)){while($row=mysql_fetch_array($res)){$qtype1=$row[0];}}

In the above code i take the type corresponding to its id.I have to compare if the type is in the array, and if it is some conditions should be done. please tell me how to do this.

You have to include like this php file to give connection.

<?phpinclude("config/config.php");?>

Hi, Please tell me how to store a column from db in array. My table name is qtype, and the fields in table are id & type.

$sql="select type from qtype";$result=mysql_query($sql);

I had selected the type from table.There are some 6types in type field, and i have to store all the 6 in array.How shall i do this. Any ideas please tell me.

Yes i've not written for answer button.

function reply_click(clicked_id){alert(clicked_id);var clicked_id=this.id;}function validate(){/*var a=document.getElementById('1').value;alert(a);var b=document.getElementById('2').value;alert(;*/if(clicked_id=="ques"){alert("hai");var quest1=document.getElementById('ques1').value;var board_txt=document.getElementById('board_txt').value;var subject_txt=document.getElementById('subject_txt').value;var cno=document.getElementById('cno').value;var pno=document.getElementById('pno').value;short_type=document.getElementById('short_type');short_type1=short_type.options[short_type.selectedIndex].value;quest1=trim(quest1);board_txt=trim(board_txt);subject_txt=trim(subject_txt);pno=trim(pno);cno=trim(cno);if(quest1==""){alert("Please enter Question");document.getElementById('ques1').focus();return false;}else if (board_txt==""){alert("Please Select Board");document.getElementById('board_txt').focus();return false;}else if (subject_txt==""){alert("Please Select Subject");document.getElementById('subject_txt').focus();return false;}else if( pno==""){alert("Please enter valid Page No");document.getElementById('pno').focus();return false;}else if (cno==""){alert("Please Select Chapter No");document.getElementById('cno').focus();return false;}}else if(clicked_id=="ans"){alert("hhh");var stmt1=document.getElementById('stmt1').value;}}

But now its seems like when clicking answer button, it doesnt come to the elseif condition.I dnt knw wat i did wrong in that part. please tell me.

as replied, what's the problem? Where is your javascript code? What are you stuck on?

function reply_click(clicked_id){alert(clicked_id);var clicked_id=this.id;}function validate(){/*var a=document.getElementById('1').value;alert(a);var b=document.getElementById('2').value;alert(;*/if(clicked_id=="ques"){alert("hai");var quest1=document.getElementById('ques1').value;var board_txt=document.getElementById('board_txt').value;var subject_txt=document.getElementById('subject_txt').value;var cno=document.getElementById('cno').value;var pno=document.getElementById('pno').value;short_type=document.getElementById('short_type');short_type1=short_type.options[short_type.selectedIndex].value;quest1=trim(quest1);board_txt=trim(board_txt);subject_txt=trim(subject_txt);pno=trim(pno);cno=trim(cno);if(quest1==""){alert("Please enter Question");document.getElementById('ques1').focus();return false;}else if (board_txt==""){alert("Please Select Board");document.getElementById('board_txt').focus();return false;}else if (subject_txt==""){alert("Please Select Subject");document.getElementById('subject_txt').focus();return false;}else if( pno==""){alert("Please enter valid Page No");document.getElementById('pno').focus();return false;}else if (cno==""){alert("Please Select Chapter No");document.getElementById('cno').focus();return false;}}else if(clicked_id=="ans"){alert("hhh");var stmt1=document.getElementById('stmt1').value;}}

When clicking the answer button it didnt come the elseif condition.

ok. Then please tell me. I'm having a form with two buttons.

<input type="submit" name="question" id="1" value="question" onclick="reply_click(this.id)" /><input type="submit" name="answer" id="2" value="answer" onclick="reply_click(this.id)" />

I've to write the javascript by checking the conditions for both buttons sepeately in one validate function.

Is it possible to have more than one function inside a function. please tell me

ya sure. The following is my form and script

<form action="a.php" method="post" name="choose" onSubmit="return validate();"><table align="center" border="1" width="850" height="500" bgcolor="FFF5EE" ><tr><td><table align="center" bgcolor="">  <tr><td align="center" colspan="10"><img src="img/laugh.gif" alt="Smiley" /></td></tr>  <tr><td align="center" style="color:#FF0000;
