Your HTML would need to be something like the following for this to work as you want:

<input type="hidden" name="x[]" value="1"> 
<input type="hidden" name="x[]" value="2">
<input type="hidden" name="x[]" value="3">

[xiongbin]

<form name="form1" method="post" action="c.php">
<input type="hidden" name="x" value=" <? print_r(array("1"=>1,"2"=>2,"3"=>3));?>">
<input type="submit" name="Submit" value="送出">
</form>
c.php

<?

foreach($_POST[x] as $key)
echo $key;

?>

help me to runing this... ?

Welcome to WebmasterWorld xiongbin,

are you sure that you don't need what eelix posted?

<form name="form1" method="post" action="c.php">
<input type="hidden" name="x[]" value="1">
<input type="hidden" name="x[]" value="2">
<input type="hidden" name="x[]" value="3">
<input type="submit" name="Submit" value="送出">
</form>

if not then you may need to add some more info

do you need to build the form from an array of values?

[xiongbin]

how can i post special array ...

[jatar_k]

you could post it as a string and separate somehow

<?
$thearray = array("1"=>1,"2"=>2,"3"=>3));
$thestring = implode('-',$thearray);
?>
<form name="form1" method="post" action="c.php">
<input type="hidden" name="x" value=" <? echo $thestring; ?>">
<input type="submit" name="Submit" value="送出">

then

$thearray = explode('-',$_POST['x'];
print_r($thearray);

should work, didn't test it

[xiongbin]

post array from form ,should easy to get array_key and array_value.

as like $_SESSION

[xiongbin]

any way? haha

[jatar_k]

maybe serialize it then

cookie?

I assume you can't use sessions

i don't completey understand the reason you are doing what you're doing

[xiongbin]

if have a array
$array=array("a"=>array("b"=>3,"d"=>"this"),"xs"=>2,"m"=>array(array(1,2,3)));

how can i use form post the $array to another web page

[coopster]

serialize [php.net] it and put it in a hidden form field, or use sessions, or perhaps even a cookie. The key here is to serialize the array before and unserialize it before you go to use it once again.

[xiongbin]

please give me a bit code ..

ahaha

[jatar_k]

take a look at the manual

serialize() [php.net]

[xiongbin]

tks...

[xiongbin]

can you help me any another way...

ahaha ..

[coopster]

You mean serialize is not going to work for you? You may have to offer some more details ...

[eelixduppy]

If you are looking for a serialize code example, this is the best I can give you. If this isn't what you are looking for you are going to have to elaborate on your issue.

The following will add the proper data to the hidden input field:

<form name="form1" method="post" action="c.php"> 
<?php
$array = array('one','two','three');
printf('<input type="hidden" name="x" value="%s" />', [url=http://www.php.net/htmlentities]htmlentities[/url]([url=http://www.php.net/serialize]serialize[/url]($array)));
?>
<input type="submit" name="Submit" value="送出">

And then on c.php, your action page, you are going to have to get the data back in the following way:

$theArray = [url=http://www.php.net/unserialize]unserialize[/url]([url=http://www.php.net/html-entity-decode]html_entity_decode[/url]($_POST['x']));
echo '<pre>'; [url=http://www.php.net/var-dump]var_dump[/url]($theArray); echo '</pre>';
