[Resolved] Passing array from a form to a php script

jsaradhi

Hi,

I'm trying to send two arrays from a form using post method from one php script to another php script. I haven't worked with arrays before...could you help?

Thanks in advance....

Ok. Let's see what your doing...

jsaradhi

<?
$z=0;
$sqlquery = "select Name, URL, ID from $table where $word like '1' order by Name";
$result = mysql_query($sqlquery) or die("Query failed");

print "<form method='post' action='addcart1.php'>";
while ($line = mysql_fetch_array($result, MYSQL_ASSOC))
{
$id = $line['ID'];
$link = "http://www.egr.msu.edu/~envirotools/cgi-bin/addcart.php?tabletype=1&id=$id";
$name = "tabletype[$z]=1&id[$z]=$id";
print "<input type='checkbox' name=$name align='right'>";
print "<a href=".$line['URL']." target=$target'>".$line['Name']."</a>";
$z++;
}
print "<input type='submit' value='Add to cart' class='select'>";
print "</form>";
?>

i need to pass id[$z] to another script and retrieve that array in the other script...i'm not sure how to trap that array in the other script...

thanks in advance...

// change these
 $name = "tabletype[$z]=1&id[$z]=$id";
print "<input type='checkbox' name=$name align='right'>"; 

// to this
print "<input type='checkbox' name='tabletype[".$z."]'>";
print "<input type='checkbox' name='id[".$z."]' value='".$id."'>";

thanks for the reply lord.

but i can not have 2 check boxes. i have to have only one checkbox and that tabletype[$z] thing can b gotten rid of....my issue here is how to trap this array in the other script...addcart1.php! i never did this before so wanted some help...please?

thanks...

The array isn't being passed doing it the way you're doing it. LordShryku's way will let you access the array in your other script. This is not to say you have to use the tabletypes checkbox, btw.

Then in your other script you can put

$trappedArray = $_POST['id'];

And $trappedArray will contain the array.

Thanks! I did that...but i have problem retrieving data from the array passed in the addcart1.php
plz see following:

<?php
$a=0;
print "In add cart<br>";
$idarray=$_POST['id'];
print $tabletype."<br>".count($idarray);
while($a<5)
{
print "<br>Inside while $a> ";
print $idarray[0]."<br>";
$a++;
}
?>

this is wat i had...just wanted to see if it works...but the followin is wat i get in the browser (one item was checked in the checkbox and hence count of idarray = 1:

In add cart

count of idarray is 1
Array ( [188] => on )
Inside while 0>

Inside while 1>

Inside while 2>

Inside while 3>

Inside while 4>

It should print that one item in the idarray right??? What am I doing wrong?

Thanks...

Hmmm...What do you get with just

print_r($idarray);

jsaradhi

This is what I get when I just do print_r($idarray); for 2 item checkboxes checked

Array ( [189] => on [190] => on )

🙁
????????????

Thanks for the help...

jsaradhi
