retrieve an array from another page sent by a form - php

Question

I would like to pass an array from a form by changing its values (inputs).
the user can change the values ​​of the inputs,
how could retrieve the array changed?
for example...
<?php $vector = array("product1" => 150, "product2" => 120); ?>
<table>
<form action="page2.php" method="get">
<?php foreach ($vector as $key => $value) {
echo "<tr><td>Product: $name</td><td><input type='text' name='$key'
value='$value'/>
</td>";
}
<tr>
<td><input type="submit" name="process" value="Submit" /></td>
</tr>
</form>
</table>
?>
// on the other page...page2.php
if (isset($_GET['process'])){
$foo = $_GET[$vector]; // the array i want
echo var_dump($foo);
}

Answer 1

HTTP, by design, allows arrays through POST/GET. Simply have the related items with the same name and ending with two opposing square brackets, like so:
<input type="text" name="data[]" value"First"/>
<input type="text" name="data[]" value"Second"/>
And on the server...
print_r($_REQUEST['data']);
Prints...
Array
(
[0] => First
[1] => Second
)
Pretty convenient, hmm?

Parameters are passed as an array form. So you have to parse the requested variables
Here is the revised version of your code.
<?php $vector = array("product1" => 150, "product2" => 120); ?>
<table>
<form action="page2.php" method="get">
<?php foreach ($vector as $key => $value) {
echo "<tr><td>Product: $name</td><td><input type='text' name='$key'
value='$value'/>
</td>";
}
<tr>
<td><input type="submit" name="process" value="Submit" /></td>
</tr>
</form>
</table>
?>
// on the other page...page2.php
if (isset($_GET['process'])){
unset($_GET['process']);
$foo = $_GET ;
echo var_dump($foo);
}

Answer 3

Try to just make it
$foo = $_GET ;
If you don't want the 'process' to be in the array, first call
unset($_GET['process']);
