How to post multiple fields values when clicking over a checkbox - php

Question

I am working in a small project and I have a code to do a multiple post of fields values when clicking over a check box. I have a table which lists classes and time. I need to know how to click over a checkbox and send class and time values at same time using a loop.
This is driving me crazy. I have spent hours and I can't figure out how to send multiple values at same time. When I check all the values, it works perfect but if I click one or two values, I always get a wrong time value shown.
Here is the PHP code, I am using:
if(isset($_POST['submit'])){
if((!empty($_POST['class'])) && (!empty($_POST['time']))) {
$checked_count = count($_POST['class']);
echo "You have selected following ".$checked_count." option(s): <br/>";
// Loop to store and display values of individual checked checkbox.
for ($i=0; $i < $checked_count; $i++) {
echo $_POST['class'][$i]. " ";
echo $_POST['time'][$i]. "<br>";
}
}
}
else{
echo "<b>Please Select At least One Option.</b>";
}
Here is my HTML CODE:
<form action="checkclass.php" method="post">
<label class="heading">Select Your Technical Exposure:</label><br />
<tr>
<td><input type="checkbox" name="class[]" value="C/C++"><label>C/C++</label></td>
<td><input type="text" name="time[]" value="1" width="15"><br /></td>
</tr>
<tr>
<td><input type="checkbox" name="class[]" value="Java"><label>Java</label></td>
<td><input type="text" name="time[]" value="2" width="15"><br /></td>
</tr>
<tr>
<td><input type="checkbox" name="class[]" value="PHP"><label>PHP</label></td>
<td><input type="text" name="time[]" value="3" width="15"><br /></td>
</tr>
<tr>
<td><input type="checkbox" name="class[]" value="HTML/CSS"><label>HTML/CSS</label></td>
<td><input type="text" name="time[]" value="2" width="15"><br /></td>
</tr>
<tr>
<td><input type="checkbox" name="class[]" value="LINUX"><label>UNIX/LINUX</label></td>
<td><input type="text" name="time[]" value="3" width="15"><br /></td>
</tr>
<input type="submit" name="submit" Value="Submit"/>
</form>
If I check all the values. I get the following result:
Class Time
C/C++, 1
Java, 2
PHP, 3
HTML/CSS, 2
UNIX/LINUX, 3
If I only check the UNIX/LINUX class I get:
Class Time
UNIX/LINUX, 1
I get 1 for LInux time when it should be 3. I think the time field takes the first position in the array when click just one class.
How do I relate time and class values so that whole values in a row are posted at same time. I really want to do a multiple insert but I think solving this will help me.
I will appreciate any help with this matter.

Try this:
PHP Code:
<?php
if(isset($_POST['submit'])){
if((count($_POST['class']) > 0) && (count($_POST['time']) > 0)) {
$checked_count = count($_POST['class']);
echo "You have selected following ".$checked_count." option(s): <br/>";
// Loop to store and display values of individual checked checkbox.
foreach ($_POST['class'] as $k => $v) {
echo $_POST['class'][$k]. " ";
echo $_POST['time'][$k]. "<br>";
}
} else {
echo "<b>Please Select At least One Option and the Number of Years of Technical Exposure.</b>";
}
}
?>
HTML Code:
<form action="checkclass.php" method="post">
<label class="heading">Select Your Technical Exposure:</label><br />
<tr>
<td><input type="checkbox" name="class[0]" value="C/C++"><label>C/C++</label></td>
<td><input type="text" name="time[0]" value="1" width="15"><br /></td>
</tr>
<tr>
<td><input type="checkbox" name="class[1]" value="Java"><label>Java</label></td>
<td><input type="text" name="time[1]" value="2" width="15"><br /></td>
</tr>
<tr>
<td><input type="checkbox" name="class[2]" value="PHP"><label>PHP</label></td>
<td><input type="text" name="time[2]" value="3" width="15"><br /></td>
</tr>
<tr>
<td><input type="checkbox" name="class[3]" value="HTML/CSS"><label>HTML/CSS</label></td>
<td><input type="text" name="time[3]" value="2" width="15"><br /></td>
</tr>
<tr>
<td><input type="checkbox" name="class[4]" value="LINUX"><label>UNIX/LINUX</label></td>
<td><input type="text" name="time[4]" value="3" width="15"><br /></td>
</tr>
<input type="submit" name="submit" Value="Submit"/>
</form>
It worked for me. Let me know if it worked for you.
