数组没有发布到php

Question

HTML

<link rel="stylesheet" type="text/css" href="<?php echo CSS_URL ?>modal.css" /> 
   <form id="postinfo" action="" method="POST">
    <input type="hidden" name="technician" value="<?php echo $technician; ?>">
       <input type="hidden" name="custnum" value="<?php echo    htmlentities(serialize($customerNum)); ?>">
       <input type="hidden" name="meternum" value="<?php echo htmlentities(serialize($meterNumbers)); ?>">
       <input type="hidden" name="remcred" value="<?php echo htmlentities(serialize($remCreditArray)); ?>">
       <input type="hidden" name="visitdate" value="<?php echo htmlentities(serialize($dateArray)); ?>">
        <a href ="<?php echo PROCESS_URL; ?>create_maint_token_excel.php" onclick="document.getElementById('postinfo').submit();">
                <img src="<?php echo IMAGE_URL ?>Excel.png" name="Print Excel" title="Print Excel" alt="Print Excel" /></a>

   </form>

PHP

$customerNum = unserialize($_POST['custnum']);
$meterNumbers = unserialize($_POST['meternum']);
$remCreditArray = unserialize($_POST['remcred']);
$dateArray = unserialize($_POST['visitdate']);
$technician = ($_POST['technician']); 

I have tried numerous ways of posting these arrays to a php page but the page keeps telling me that custnum, meternum, remcred and visitdate are undefined.

I have tried using a form action and post, I have tried to use a piece of javascript and I keep getting the same problem, why is this not posting?

I have also tried using $_GET instead of $_POST on php page to no avail.

<a href ="<?php echo PROCESS_URL; ?>create_maint_token_excel.php" onclick="document.getElementById('postinfo').submit();">

This will not work, the submit will go into nirvana and you will be taken to the PHP page without the variables. You are doing two requests at once and your browser will go to the one without the form variables.

Try changing your form to this:

<form id="postinfo" action="<?php echo PROCESS_URL; ?>create_maint_token_excel.php" method="POST">

And your Link to this:

<a href ="#" onclick="document.getElementById('postinfo').submit();">

This should submit the form correctly without following the link.

Alternatively use a propper <input type="submit" /> button, you can add the image to it with CSS.
