Not exactly... basically I want it to work like a calculator and the submit is the equal button. How can I get it so that when the submit button is hit... the total is then shown?
-
I only want it to return after the submit button is hit... because i'm going to be adding equations such as 1 number times another + another and then the user hits submit and the total prints out... how can I do this?echo "<input type='text' name='miles' value='" . $miles . "' size='1' maxlength='3' />";echo "<input type='text' name='speed' value='' size='1' maxlength='3' />";echo "<input type='submit' value='Submit' />";
Well, that will return the value in the first textbox if I understood your question correctly.
-
What I'm trying to get it to do is the user inputs a value into the first textbox... submit the data... and then the last echo statement returns the value on the same page. The value shows in the textbox... its returning it on the same page.What do you mean it won't show the value in the first text box?Do you mean it won't show the value at all or it won't show the value inside the text box? -
Why doesn't this want to show the value in the first text box when the button is submitted?

Ok... i understand now... thanks!!

I thought the is_numeric() function returns if the number is even or not?
-
I can't seem to get the second box to change depending on what it selected in the first box... whats wrong?

Is it something like this:$number = 5;if(is_numeric($number) AND getType($number))echo "<br />The number ", $number, " is even.";elseecho "<br />The number ", $number, " is odd.";???
-
I've searched the site but I am unable to find as to how to put it into a conditional statement.
-
I need to use a conditional statement to check if a number is an integer and that it is also even. I've never used the getType or is_numeric inside a conditional statement before. Can somebody help me out?

Thanks... this helps a lot. I prefer php over javascript... renders a lot faster!It is better to do this using javascript, because values in second select box change without reloading the page.Since you requested in php forum, here is an example in php.<html><body><form action='' method='get'>Computer: <select name='selectbox1' id='selectbox1' onchange="document.getElementById('selectbox2').selectedIndex='0';"><option value='c1'>Computer 1</option><option value='c2'>Computer 2</option><option value='c3'>Computer 3</option></select> Speed: <select name='selectbox2' id='selectbox2'><?if (isset($_GET["selectbox1"])){ echo "<option value=''>Select speed</option>"; switch ($_GET["selectbox1"]) { case 'c1': echo "<option value='c1speed1'>C1 S1</option>"; echo "<option value='c1speed2'>C1 S2</option>"; echo "<option value='c1speed3'>C1 S3</option>"; break; case 'c2': echo "<option value='c2speed1'>C2 S1</option>"; echo "<option value='c2speed2'>C2 S2</option>"; echo "<option value='c2speed3'>C2 S3</option>"; break; case 'c3': echo "<option value='c3speed1'>C3 S1</option>"; echo "<option value='c3speed2'>C3 S2</option>"; echo "<option value='c3speed3'>C3 S3</option>"; break; }}?></select> <input type='submit' value='submit' ></form><br><?if (isset($_GET["selectbox1"]) && isset($_GET["selectbox2"]) && $_GET["selectbox2"]!=""){ echo "Computer: ".$_GET["selectbox1"]."<br>"; echo "Speed: ".$_GET["selectbox2"];}?></body></html> -
I have a form with a select of thee options for "computer" and another select for three options for "speed". I have it written like this for example:
echo "<option value='c1'>", $pc, "</option>";
How can I say if the user clicks on one of the three options (lets say the first one), that in the second select the three options change to match that of the first selection?

I'm having a brain ######. I need the the script to show all of the data but in the last column i need it to muliply what it has there already by another amount in a nother column but same row. And I need this done for all of the rows... can somebody blow the ###### out of my head?

I want to try and do it in php and stay away from javascript though. This is what i ahve so far... do u think it can be adapted because this isn't working...Depending on what you want it to do when clicked, I think you're looking for javascript, not php. Specifically with javascript, the onclick function.<?php $picture = "images\blue-carry.jpg"; echo "<a href='images\blue-carry.jpg?link = 1'><img src='$picture' border='0' /></a>"; if($_GET['link'] == 1) { $picture = "images\blue-ebook.jpg"; echo "<img src='$picture' border='0' />"; } ?> -
how can I say "if this link is clicked" in an if statement?

My textarea will not wrap in FireFox... any suggestions?

I've installed php and Apache... but apache is giving me one error when i try to restart it... could that be the error?I think i know the problem. The error is stating that it won't take a dll file to the server but when in fact i don't have a server set up yet. So once I set a server up on my own machine... then it will take it to the server and therefore allowing me to test php on my machine. I think I got it. thanks!!Either that, or install a webserver and PHP on your local machine to develop with. -
So before i actually make a page with php, its best to get the domain name and server space and then start testing the php?If it looks exactly the same, where you see the PHP code, then PHP is not getting executed. You need to run the page from the server, you cannot open a local PHP file in your local web browser and have the code execute it, you need to access it through http. -
Looks the same as my code in the editor.When you go to View->Source in the browser.

Thats the thing, I do not see the total shown after the submit is hit. Its like it refreshes the screen and the values in the text box are gone and the zero disappears. Any reason why its doing this for me?
