Passing Array

Cogen

Hi all,

I'm sure this is a pretty basic thing, however I've searched for the result with no luck, and was just wondering if someone could give me some advice.

I want to pass an existing array in php through a post method form. This is what I have so far.

//The $Variation array is setup already before doing this.
echo "<input type=\"hidden\" name=\"VariationName[]\" value=\"".$VariationName[]."\" />\n";

However it's not working properly. How do I submit an array to a post form, then put it back into a php array on the following page?

I doubt it works that way

instead you have to create multiple input fields with the name array[]
and their value is $array[0] ...

just write a loop, which does that for you

Thanks for the return ir4z0r, although I'm not sure how to accomplish that.

Basically what I'm doing is I have an input text field. The user types something in and clicks on the add button. When the user does that, the form submits back to the same page, allowing the user to enter another value into the text field. The problem is everytime the user does this, I need to keep the previously added values in an array, and just add the latest value to it. When the user is done adding, they click on the next button instead of the add button, and they are taken to another page which also gets passed the entire array, so I can add them all into a database.

so you got your array, then do the following:

$VariationName = $_POST['VariationName'];

// the next entry's name is "newinput" and is added to the array
$VariationName[] = $_POST['newinput'];

for ($i=0; $i < sizeof($VariationName)
{
  echo '<input type="hidden" name="VariationName[]" value="' . $VariationName[$i] . '" />\n';
}

untested
