Some doubt about $_POST

[simongcc]

Hi!

I have a php form in which some textareas area available.
When the form is submitted, the variable will then pass to another
php file called api_something.php

For instance, the name/id of the text area are:
langContent1
langContent2
langContent3

So, in api_something.php, the variable can be read as following:
$langContent1 = $POST["langContent1"];
$langContent2 = $POST["langContent2"];
$langContent3 = $_POST["langContent3"];

I wonder. If I have more similar variable in $langContent series such as
$langContent4, 5, 6....

Is it possible to use pass an array of variables instead 1 by 1?

I have tried session to store and pass the variable. However, if I change the content in langContent1,2,3 , the changed information is only reflected in $_POST. Is it possible to treat these variables more intelligently? I have tried a bit with limited knowledge. I think I should have asked some expert and avoid to flog a dead horse.

Thanks a lot.

What you can do is modify your html as follows:

<form action="api_something.php" method="POST">
<input type="text" value="one" name="langContent[]">
<input type="text" value="two" name="langContent[]">

<input type="submit" value="send">
</form>

On the receiving php file you'll have access to that variable with $POST['langContent'], but remember that you're receiving an array, so for example, for the code above, you would access the first variable with

$_POST['langContent'][0]

and the second one with

$_POST['langContent'][1]

etc. You could also do:

foreach($_POST['langContent'] as $var)
{

  //Do something with $var

}

Anyway, I hope this was helpful.
Salut.
