Force Blank Inputs To Submit

[ShadowMage]

I have a bunch of inputs set up to submit in an array, ie:

<input type='text' name='length[]' value='' />

These inputs are submitted to a PHP script which loops through each of them and constructs a semi-colon delimited string, ie:

for ($x=0; $x<5; $x++) {   if ($x > 0) {	  $tmpLengthString.=';';   }   if (isset($_POST['length'][$x])) {	  $tmpLengthString.=str_replace(',', '', $_POST['length'][$x]);   }}

It is supposed to produce a string that, when exploded on the semi-colon, will create an array of 5 elements.Works great when the inputs are all filled in from left to right up to a certain point. Ie, length[0], length[1], length[2] are filled in but length[3] and length[4] are not. (produces '0;1;2;;')The problem appears when the first one (or more) are not filled in. Ie, length[0] and length[1] are blank, but length[2-4] are filled in. (produces '2;3;4;;' when it should produce ';;2;3;4')It also happens if one is skipped. Ie, 0-2 filled, 3 blank, 4 filled. (produces '0;1;2;4;' when it should produce '0;1;2;;4') The issue is that the blank inputs don't submit to PHP. When 0-2 are filled they are populated in their respective places in $_POST['length'][0-2] but if, for example, 0-2 are left blank, then 3 will be put in $_POST['length'][0].Does that make sense? Is there a way to force those blank inputs to submit?

Put a number between the square brackets:

<input type='text' name='length[0]' value='' /> <input type='text' name='length[1]' value='' /><input type='text' name='length[2]' value='' />

Wow! Who'da thunk it could be so simple! Thanks, Ingolme!
