adding values into an array

[Anon]

Ez all,

I'm trying get a simple form to add to an array.

All I want to do is send a name from a form field into an array. And then progressively add more and more names into the same array buy entering and submitting them in the form.

I've thought long and hard about it but everytime i submit a new name it just replaces the old name with the new name rather than adding it to the names already stored.

This is what ive done but even I can see this is not right... Please help...

<form method="POST" action="<?php echo $PHP_SELF ?>">
<input type="hidden" name="action" value="add">
Name<input type="text" name="name2" size="20">
<input type="submit" value="Submit" name="B1">
</form>

<?
$store_info[] = "";

while(list($ElementIndexValue, $ElementContents) = each($store_info))
{
echo "<br> $ElementIndexValue - $ElementContents";
}

function add_array()
{
global $PHP_SELF, $name2, $store_info;

$numrow = count($store_info);
$store_info[$numrow] = $name2;
}

if($action == "add")
{
add_array();
}
?>

You'll have to store the array somewhere: a file, cookie, hidden fields, query string, somewhere...

Ok wicked so if i put the array into the form as a hidden field do you think that would work?

Ive changed the code to this:

<form method="POST" action="<?php echo $PHP_SELF ?>">
<input type="hidden" name="store_info" value="<?php echo $store_info ?>">
Name<input type="text" name="name" size="20">
<input type="submit" value="Submit" name="B1">
</form>

<?
$store_info[] = "$name";

while(list($ElementIndexValue, $ElementContents) = each($store_info))
{
echo "<br> $ElementIndexValue - $ElementContents";
}
?>

The array should list each new added name as you add it in the form. At the moment all it does is replace the existing name with the new name???

Are you trying to store this data permanently? Your script as written will just add $name2 to index 1 of the array $store_info. It is not stored anywhere after the script has completed. If you need to store this permanently you should use a database or a text file. If you just need to store it temporarily to goto another page then you need to pass it via GET or POST or store it as a session variable.

This code doesnt actually have any function. Im just trying to get to grips with it... When I use it in a real scenario the array will be stored either as Session variable or as database content... all I am trying to achieve at the moment is adding to the array so everytime i submit a name the array grows and lists the additional names...

Then you need to your alter code the keep the array on subsequent requests. You can do this by dynamically adding the existing array as hidden fields to the form or starting a session or using a database. The way your code is now the array is re-intialised on each page hit.

cheers mate.. I got it sorted by declaring the store_info as a session variable right at the top of the page!!
