[RESOLVED] check to see which button is clicked in php, but how about the image button?

[searain]

for example, if i have three submit buttons, submit1, submit2, submit3, in a form. and depends on which button is clicked the action will be different.

in php

i will simply use

if (isset($POST['submit1']))
{
}
elseif (isset($POST['submit2']))
{
}
elseif (isset($_POST['submit3']))
{
}

This will work if these three submit buttons are regular form submit buttons. But if I am using image button as the submit buttons, then the above php codes are not working.

So how php to tell which image button is clicked? Thanks!

<form action="" method="POST">
<input type="image" name="submit1" src="submit1.gif"><br>
<input type="image" name="submit2" src="submit2.gif"><br>
<input type="image" name="submit3" src="submit3.gif">
</form>

<?php
if ($_POST)
{
	foreach ($_POST as $key => $value)
	{
		if (strpos($key, '_x') !== false)
		{
			$explode = explode('_', $key);
			echo 'you pressed ' . substr($explode[0], 0);
			break;
		}
	}	
}
?>

What is "_x" in the name?

I also found answer to this question from this forum's archive. That might also answer loganK's question
