Can a checkbox value be an array?

[mattcairns]

Does anyone know whether or not it is possible to set the value of a checkbox as an array? And if so how to do it. I've tried this, but with no luck.

 

<?
##CREATE VARS
$one = array("this1", "that1", "what1");
$two = array("this2", "that2", "what2");
$three = array("this3", "that3", "what3");
$four = array("this4", "that4", "what4");

print "
<form id='form1' name='form1' method='post' action=''>
<input type='checkbox' name='files[]' id='files' value='$one' />
One<br />
<input type='checkbox' name='files[]' id='files' value='$two' />
Two<br />
<input type='checkbox' name='files[]' id='files' value='$three' />
Three<br />
<input type='checkbox' name='files[]' id='files' value='$four' />
Four<br />
<input type='submit' name='Submit' id='Submit' value='Submit' />
</form>";
?>

Yes you can

 

foreach ($one as $value){echo "<input type='checkbox' name='filen[]' value='".$value."' checked>$value<br>";}

thanks, but unless i don't understand, i don't think that's what i'm looking for. i want the value of a checkbox to be an array. so the final result on the process would be a nested array, if that makes sense.

Maybe like this:

<?php
$array = array('this','is','my','array');

echo '<input type="checkbox" name="files[]" id="files" value="';
print_r($array);
echo'">';
?>

 

untested...

Values have to be in text/numbers only they cannot hold array values. However what you could do is this:

<?php
$one = array("this1", "that1", "what1");

echo '<input type="checkbox" name="files[]" id="files" value="' . implode(',', $one) . '">';
?>

That will produde this as the checkbox's value:

this1,that1,what1

 

Then in the processing script that retrieves the checkbox's value you can use explode to put it's value back into an array.

 

Eg:

<?php

$checkbox1_value_array = explode(',', $_POST['files'][0]);

print_r($checkbox1_value_array);

?>
