Getting Internal Server Error on Submit

[carstorm]

Whenever I hit submit I get an internal server error. Here is the code:

<?php $modsToBeChecked = str_replace(
"\r",
"\n",
str_replace( "\r\n", "\n", $_POST[ 'modsToBeChecked' ] )
);
$modsToBeChecked = explode( "\n", $modsToBeChecked );


var_dump( $modsToBeChecked );?>

$modsToBeChecked is passed in from a textarea form. It is suppose to treat each line in the textbox as one element of the array. Here is the form code in case you need it:

<form  action=""><textarea name="modsToBeChecked" rows="25" cols="50"></textarea>
<input type="submit">
</form>

Whenever I hit submit I get an internal server error.

Check your severs error logs to see why you are getting that error. Or add the following after the opening PHP tag line to see the error message(s) in the browser.

ini_set('display_errors', 1);
error_reporting(E_ALL);

Ah it says "Notice: Undefined index: modsToBeChecked" line 66 which is this line

 

str_replace( "\r\n", "\n", $_GET[ 'modsToBeChecked' ] )

 

Is that the wrong way to get the form data?

Depends, are you submitting the form using GET or POST? Your earlier code indicated $_POST but now you are trying to access $_GET

[WinstonLA]

Before using $_POST[ 'modsToBeChecked' ] you need check if this element is exists

if(isset($_POST[ 'modsToBeChecked' ])) {
    //Element exists, you may use it
}

Sorry about the confusion. In the original post I have the form using get yet the PHP looking for post. It is using get.

 

 

Before using $_POST[ 'modsToBeChecked' ] you need check if this element is exists

if(isset($_POST[ 'modsToBeChecked' ])) {     //Element exists, you may use it }

Now my code is:

 

if(isset($_GET[ 'modsToBeChecked' ])) {

$modsToBeChecked = str_replace(

"\r",

"\n",

str_replace( "\r\n", "\n", $_GET[ 'modsToBeChecked' ] )

);

$modsToBeChecked = explode( "\n", $modsToBeChecked );

 

var_dump( $modsToBeChecked );

}

 

 

I'm not getting any errors generated by php yet still getting a  internal server error!

still getting a  internal server error!

Then you will need to look at your servers error logs

[QuickOldCar]

if(isset($_GET['modsToBeChecked'])) {
$modsToBeChecked = preg_replace(array("/\r\n+/", "/\r+/", "/\n+/"), "/n",trim($_GET['modsToBeChecked']));
$modsToBeChecked = explode("/n", $modsToBeChecked);

var_dump($modsToBeChecked);
}

You can probably improve it more depending on spaces in mod names, wasn't sure what your data was

I would first check the error logs,as was mentioned earlier, and then work on tackling that php page.

I don't see an action url set in your form, which means by default it just submits to the same page. Make sure they are otherwise you need to set the action attribute in your form to where the script is located.

As already stated there are none.

 

if(isset($_GET['modsToBeChecked'])) { $modsToBeChecked = preg_replace(array("/\r\n+/", "/\r+/", "/\n+/"), "/n",trim($_GET['modsToBeChecked'])); $modsToBeChecked = explode("/n", $modsToBeChecked); var_dump($modsToBeChecked); }

Ya mod names can have spaces hence why I use each line as an element.

The php script is on the same page hence why there is no action attribute.

[mikosiko]

could you post a REAL example of the content of modsToBeChecked ?

 

An Internal Server error normally is logged... are you sure that you are looking the right logs files?

 

The last code that you posted works fine on testing, therefore seems that the POSTED code is not the issue here. Are you psoting the WHOLE code that you are using?...
