[SOLVED] Can't use $_POST but $_GET Works

[peleg]

In this form:

 

<form method="POST" id="frmdlgAdd" name="frmdlgAdd" action="destinationadd.php">

<p>Destination</p>

<input type="text" name="inpAddDestination" id="inpAddDestination" value="Acme">

<p>Address</p>

<input type="text" name="inpAddAddress" id="inpAddAddress" value="Acme Address">

</form>

 

in destinationadd.php, the $_POST is empty. If I simply change to using GET in the form and the PHP, it works, so I don't think the problem is my PHP code (I only change two $_POST's to $_GET and it works). Why can't I use POST? The PHP version is 5.2.9. Is this some sort of configuration problem?

 

Thanks.

So if you change

 

$var1 = $_POST['inpAddDestination'];

$var2 = $_POST['inpAddAddress'];

 

to

 

$var1 = $_GET['inpAddDestination'];

$var2 = $_GET['inpAddAddress'];

 

without changing the form method to GET it does work?

please post the relevant code in destinationadd.php, thanks

Do print_r[$_POST] to check if it contains your values or not. It MUST be your php code that is wrong since the form isn't.

Here is the PHP code:

 

<?php

// *****************************************************************************

//

// Add a new Destination

//

// *****************************************************************************

 

include 'inc/tas_db_functions.php';

 

echo 'Method is: ' . $_SERVER['REQUEST_METHOD'] . "\n";

echo "GET ---->\n";

print_r($_GET);

echo "\n";

echo "POST ---->\n";

print_r($_POST);

 

$db = new DBAccess;

 

$db->insert_row(

'Destination_tbl',

array(

'Destination' => quote($_GET['inpAddDestination']),

'Address1' => quote($_GET['inpAddAddress'])

)

);

 

?>

 

and the response when the form uses GET (in Firebug) is:

Method is: GET

GET ---->

Array

(

    [inpAddDestination] => Acme

    [inpAddAddress] => Acme Address

)

 

POST ---->

Array

(

)

 

and when I simpy change GET to POST in the form:

Method is: GET

GET ---->

Array

(

)

 

POST ---->

Array

(

)

 

I just noticed, and I double-checked it, that when I POST, the PHP still reports the Request Method as GET. I got a feeling that has something to do with it. Firebug, however, does think that a POST is being done, so it looks like my PHP is missing something.

What does a phpinfo(); statement show for post_max_size? What is the entire code of the page with your form on it?

[.josh]

$db->insert_row(
   'Destination_tbl',
   array(
      'Destination' => quote($_GET['inpAddDestination']),
      'Address1' => quote($_GET['inpAddAddress'])
      )
);

 

so if you have your form as method='post' did you change those two $_GET's to $_POST[...] ?

What does a phpinfo(); statement show for post_max_size?

 

It's 8M. That ought to be enough for this instance.

What is the entire code of the page with your form on it?

 

Well, it's part of a YUI Dialog...

 

// Add button click handler

var hAdd = function() {

var oData = this.getData();

var intID;

say('Add oData', oData);

this.hide();

this.submit();

};

 

// configuration for dialog

var params = {

div:"dlgAdd",

header: {

text:"ADD DESTINATION",

color:"green",

font:'Georgia, "Times New Roman",Times,serif',

"bold":true,

size:"1.2em"

},

nextTo:"inpDestination",

bodyText:

'<form method="GET" enctype="multipart/form-data" id="frmdlgAdd" name="frmdlgAdd" action="destinationadd.php">' +

'<p>Destination</p>' +

'<input type="text" name="inpAddDestination" id="inpAddDestination" value="Acme">' +

'<p>Address</p>' +

'<input type="text" name="inpAddAddress" id="inpAddAddress" value="Acme Address">' +

'</form>',

addHandler:hAdd,

cancelHandler:function() {this.cancel();}

};

 

// create dialog

fn.AddDialog = function(oArgs) {

 

var elDivDlg, oHeader, strDiv;

 

// is default div name being overridden?

if (!fn.isDefined(oArgs.div)) {

oArgs.div = "dlgAdd";

};

 

// if div exists, we are done

if(!yud.get(oArgs.div)) {

 

elDivDlg = document.createElement("div");

elDivDlg.id = oArgs.div;

document.body.appendChild(elDivDlg);

 

fn.oAddDialog = new yw.Dialog(

oArgs.div,

{

visible:false,

context:[oArgs.nextTo, "tl", "bl"],

underlay:"none",

close:false,

modal:true,

hideaftersubmit:true,

buttons:

[

{text:"Add",  handler:oArgs.addHandler, isDefault:false},

{text:"Cancel", handler:oArgs.cancelHandler, isDefault:true}

]

}

);

 

fn.oAddDialog.setHeader(oArgs.header.text);

fn.oAddDialog.setBody(oArgs.bodyText);

fn.oAddDialog.render();

 

oHeader = oArgs.header;

strDiv = oArgs.div + "_h"

if(fn.isDefined(oHeader.color)) {yud.setStyle(strDiv, "color", oHeader.color);}

if(fn.isDefined(oHeader.font)) {yud.setStyle(strDiv, "fontFamily", oHeader.font);}

if(fn.isDefined(oHeader.bold) && oHeader.bold) {yud.setStyle(strDiv, "fontWeight", "bold");}

if(fn.isDefined(oHeader.size)) {yud.setStyle(strDiv, "fontSize", oHeader.size);}

}

 

return fn.oAddDialog;

 

};

[peleg]

$db->insert_row(
   'Destination_tbl',
   array(
      'Destination' => quote($_GET['inpAddDestination']),
      'Address1' => quote($_GET['inpAddAddress'])
      )
);

 

so if you have your form as method='post' did you change those two $_GET's to $_POST[...] ?

 

Yes. Remember that the dump of $_POST is empty.

Are you posting this through Ajax?

[peleg]

Are you posting this through Ajax?

 

YES!!! THAT'S IT!!!

 

In the code:

 

var hAdd = function() {
var oData = this.getData();
var intID;

this.hide();
this.submit();
}

 

the this.submit() looks like it should do a normal submit, but the default is to do an XMLHttpRequest. I changed the default in the setup for the YUI Dialog, and indeed, it is now POSTing the data. I've had this problem in other places but never noticed that default before or thought to look at exactly how the data was being submitted.

 

I have been fighting with this problem for a while now and I never could figure out what was wrong. Turns out it's not a PHP problem at all, but it sure looked like one when I started.

 

Thank you all very much, but especially haku because your question pointed me in the right direction.
