yes, I believe you could just do something like this:
(filename is "form_array.php" if you want to run it by itself)
<?php
if($_SERVER['REQUEST_METHOD'] === "POST"){
//submitted
//print the $_POST array
echo '<pre>';
print_r($_POST);
echo '</pre>';
//now, resave our array
$myarray = array();
for($i = 0; $i < count($_POST); $i++){
if(isset($_POST['arrayitem_' . $i])){
$myarray[$i] = $_POST['arrayitem_' . $i];
}else{
//array ended, break out of the for loop
break;
}
}
//now, print our new array, it will print out the same result as the $_POST print out
//thus, we've recreated our array.
echo '<pre>';
print_r($myarray);
echo '</pre>';
exit;
}
//not submitted
echo '<form method="post" action="form_array.php">' . "\n";
$myarray = array("item1", "item2", "item3", "item4");
for($i = 0; $i < count($myarray); $i++){
echo '<input type="hidden" name="arrayitem_' . $i . '" value="' . $myarray[$i] . '" />' . "\n";
}
echo '<input type="submit" value="pass array" />' . "\n";
?>
Now, while I was making this, I remembered that you could just build the array in the form and have it automatically send itself through the form.. I just decided to include the above example anyway! So, here is how you can do that as well, which is probably the better/easier thing to do:
(this file should be form_array2.php if you want to run it by itself)
<?php
if($_SERVER['REQUEST_METHOD'] === "POST"){
echo '<pre>';
print_r($_POST);
echo '</pre>';
//you can now reference your old array using the following:
// $_POST['arrayitem'][i] where i is the number you want to reference
//ie: let's print out all of the items in the array
for($i = 0; $i < count($_POST['arrayitem']); $i++){
echo $i . ': ' . $_POST['arrayitem'][$i] . '<br>';
}
exit;
}
?>
<form method="post" action="form_array2.php">
<input type="hidden" name="arrayitem[]" value="item1">
<input type="hidden" name="arrayitem[]" value="item2">
<input type="hidden" name="arrayitem[]" value="item3">
<input type="hidden" name="arrayitem[]" value="item4">
<input type="hidden" name="arrayitem[]" value="item5">
<input type="submit" value="submit">
</form>
hope you can make sense of it.
both scripts run fine, if you wanted to test them to see how they worked.
