So, i made a seat booking system where there are checkboxes in every seat and the user select this boxes and the seats are considered reserved.

But now i want make the user be able to give each marked seat a name. How can i do that?

seats.php

<html><head><title>Tickets</title><style>* {font-size: 11px;font-family: arial;}</style><script>function reserveSeats() {var selectedList = getSelectedList('Reserve Seats');if (selectedList) {if (confirm('Do you want to reserveselected seat/s ' + selectedList + '?')) {document.forms[0].oldStatusCode.value=0;document.forms[0].newStatusCode.value=1;document.forms[0].action='bookseats.php';document.forms[0].submit();} else {clearSelection();}}}function cancelSeats() {var selectedList = getSelectedList('Cancel Reservation');if (selectedList) {if (confirm('Do you want to cancel reserved seat/s ' + selectedList + '?')) {document.forms[0].oldStatusCode.value=1;document.forms[0].newStatusCode.value=0;document.forms[0].action='bookseats.php';document.forms[0].submit();} else {clearSelection();}}}function confirmSeats() {var selectedList = getSelectedList('Confirm Reservation');if (selectedList) {if (confirm('Do you want to confirm reserved seat/s ' + selectedList + '?')) {document.forms[0].oldStatusCode.value=1;document.forms[0].newStatusCode.value=2;document.forms[0].action='bookseats.php';document.forms[0].submit();} else {clearSelection();}}}function getSelectedList(actionSelected) {// get selected listvar obj = document.forms[0].elements;var selectedList = '';for (var i = 0; i < obj.length; i++) {if (obj[i].checked && obj[i].name == 'seats[]') {selectedList += obj[i].value + ', ';}}// no selection errorif (selectedList == '') {alert('Please select a seat before clicking ' + actionSelected);return false;} else {return selectedList;}}function clearSelection() {var obj = document.forms[0].elements;for (var i = 0; i < obj.length; i++) {if (obj[i].checked) {obj[i].checked = false;}}}function refreshView() {clearSelection();document.forms[0].action='<?php echo $_SERVER['PHP_SELF']; ?>';document.forms[0].submit();}</script></head><body><table><tr><td width="100%" align="center"><form action="<?php echo $_SERVER['PHP_SELF'];

-----------------------------

 

 

I tried the following: When the user submit the checkboxes, this is included:

 

name.php

<?php//$mysql->commit();session_start();$_SESSION['rowId'] = $_POST['rowId'];$_SESSION['columnId'] = $_POST['columnId'];echo "<h3>";echo "Please enter the name for each seat:<br><p> </p>";echo "";foreach($_POST['seats'] AS $seat) {$rowId = substr($seat, 0, 1);$columnId = substr($seat, 1);echo $rowId . $columnId . '</br><form method="post" name="input" action="pt2.php" ><input name="name" type="text"/></br>';}?><input type="submit" name="Submit" value="insert" /></form>

pt2.php:

<?php// Connect to MySQLmysql_connect("localhost", "root", "root") or die("Connection Failed");mysql_select_db("tickets")or die("Connection Failed");$name = $_POST['name'];session_start();$rowId = $_SESSION['rowId'];$columnId = $_SESSION['columnId'];$result = mysql_query("UPDATE seats SET updatedby='".$name."' WHERE rowId='".$rowId."' AND columnId='".$columnId."'") or die(mysql_error()); ?>

If the user selects only one seat, this code works like a charm. But when there's two or more, the $columnId and the $rowId doesn't change as it should, and only the name of the last checked seat is changed. Does anybody knows how i can solve this?

It looks like you're printing a new form tag for each text field, that's one problem. You should be storing the list of checkbox row/column pairs along with the form data, in a hidden input or something. For the names of the text boxes, use the column and row in the name. When you process the form, get the list of rows and columns and use that to look up the name for each one.

I'm not sure if I understood what you mean...

 

About the form tag for each text field, I edit the code, so that it doesn't repeat:

</br><form method="post" name="input" action="pt2.php" ><?php//$mysql->commit();session_start();$_SESSION['rowId'] = $_POST['rowId'];$_SESSION['columnId'] = $_POST['columnId'];echo "<h3>";echo "Please enter the name for each seat:<br><p> </p>";echo "";foreach($_POST['seats'] AS $seat) {$rowId = substr($seat, 0, 1);$columnId = substr($seat, 1);echo $rowId . $columnId . '<input name="name" type="text"/></br>';}?><input type="submit" name="Submit" value="insert" /></form>

echo $rowId . $columnId . '<input type="hidden" name="seats[]" value="' . $seat . '"><input name="' . $seat . 'name" type="text"/></br>';

 

Now you'll have an array in $_POST['seats'] that has each seat, and you can loop through that and get $_POST[$seat . 'name'] to get the name of it.

So let's say i just want to display the name of the seat. Should't this work?

 

 

<form method="post" name="name" action="pt2.php" ><?php//$mysql->commit();echo "<h3>";echo "Please enter the name for each seat:<br><p> </p>";echo "";foreach($_POST['seats'] AS $seat) {$rowId = substr($seat, 0, 1);$columnId = substr($seat, 1);echo $rowId . $columnId . '<input type="hidden" name="seats[]" value="' . $seat . '"><input name="' . $seat . 'name" type="text"/></br>';}?>   <input type="submit" name="submit" value="Submit Form"><br></form>

pt2.php

<?php// Connect to MySQLmysql_connect("localhost", "root", "root") or die("Connection Failed");mysql_select_db("tickets")or die("Connection Failed");echo $_POST[$seat . 'name'];?>

You need to define $seat before $_POST[$seat . 'name'] is going to do anything. Like I said, $_POST['seats'] will contain an array of the seats that you can loop through and get the name for each one from $_POST.

 

Like this?

<?php// Connect to MySQLmysql_connect("localhost", "root", "root") or die("Connection Failed");mysql_select_db("iamin")or die("Connection Failed");$seat = $_POST['seats'];echo $_POST[$seat . 'name'];?>

Thanks for the answers.

Alright, I'm getting the hang of it. So if I wanna send the name of the seats to the table "seatnames", in the "seatname" row:

<?php// Connect to MySQLmysql_connect("localhost", "root", "root") or die("Connection Failed");mysql_select_db("tickets")or die("Connection Failed");$name = $_POST[$seat . 'name']foreach ($_POST['seats'] as $seat){$query = "INSERT INTO seatnames(seatname) VALUES ('$name')";}?>

right?

i'm almost there!

 

 

<?php// Connect to MySQLmysql_connect("localhost", "root", "root") or die("Connection Failed");mysql_select_db("iamin")or die("Connection Failed");$name = $_POST[$seat . 'name'];foreach ($_POST['seats'] as $seat){echo $seat;$query = "INSERT INTO seatnames (seatname) VALUES ('$name')";mysql_query($query) or die(mysql_error()); }?>

For some reason it insert a blank space in the table, instead the name!
