How do I create an array and pass in $_POST
Need help pass array in $_POST

 7:05 pm on May 14, 2004 (gmt 0)

New to PHP, been coding for a month now and need help.
I have a form I created to POST back to my original PHP page. I would like to send back an array of items and their qty's as one of the?_POST variables, rather than coding name=item01, name=item02 and name=qty01, name=qty02.

How do I create an array in my script and pass it as a variable in my Post array?

Hope this makes sense and Thanks!

Basically you just stick [] after the variable name

<input type="text" name="test[]" value="This ">
<input type="text" name="test[]" value="Is ">
<input type="text" name="test[]" value="an array">

will post
[test] => Array
[0] => this
[1] => is
[2] => an array

Hope that helps

Thanks. I was hoping I could create the array in my script and pass it to the name= in the?_Post array. Is that possible?

Can you post an attempt on the code your trying to write, i'm not quite clear on what your looking for. It is late here however so my brain could be in slowmo.

I'm not entirely certain I understand either, hughie's method is how it's normally done.

alternatively, you could "serialize" the array and pass it as one string. I use this technique for saving arrays to flat files, never tried to $_post one. should work, though.

You could do something like


And then to produce the HTML you would do:

foreach ($myArray as $key => $value) {
print "<input type=\"text\" name=\"myArray[$key]\" value=\"$value\">\n";

which would print out

<input type="text" name="myArray[name]" value="John">
<input type="text" name="myArray[job]" value="Director">

For neater code I normally write this as

foreach ($myArray as $key => $value) {
printf('<input type="text" name="myArray[%s]" value="%s">',$key,$value);

Does that help?

Sorry, I've been out, thanks for this example this is what I need. I tried to create this but got a bit confused. Thanks to everyone who answered!
