Submit button with php variable

Question

<form method="post">
<input type="submit" name="'.$pTest.'" value="submit" id="submit"/>

<?php
if(isset($_POST[''.$pTest.'']))

This doesn't work if I use variable as the name of the submit button. Please some help!

Answer 1

像这样尝试

<input type="submit" name="<?php echo $pTest; ?>" value="submit" id="submit"/>

Answer 2

Your variable is doing nothing. Just echo your <input> name and catch it whith php:

<form method="post">
   <input type="submit" name="<?php echo $pTest ?>" value="submit" id="submit"/>
</form>

<?php

    if (isset($_POST[$pTest])) {

        echo 'something'

    }

?>

Answer 3

Add value to the variable first..

<?php  $pTest = 'sks'; ?>
<form method="post">
<input type="submit" method="post" name="<?php echo $pTest; ?>" value="submit" id="submit"/>
</form>

<?php
if(isset($_POST[$pTest]))
{
    echo '<script>alert("something");</script>';
}
?>

Answer 4

Just replace your quotes with double quotes :

if(isset($_POST["'.$pTest.'"]))
{
    echo 'something'
;}

Or name your input with a PHP variable :

<input type="submit" name="<?php echo $pTest; ?>" value="submit" id="submit"/>
