[Resolved] POST and REQUEST not working

dmacman1962

I have a post:

http://www.phpbuilder.com/board/showthread.php?s=&threadid=10297922

That I believe is resolved, but the issue I am now having I think is a totally new issue.

I hope this is the correct way to address this issue.

I have a form that I am passing the info to a process.php page, but none of data is being passed. No error, just no info.

I have a page that echo's the data to the screen and then to the process.php after you select the items. But when I do a:

$ID=$_REQUEST['ID'];
echo $ID;

I get nothing.

On the form page I have:

while ($row = mysql_fetch_assoc($result)) { 
		echo $ID = $row['ID'];
}
$ID = $_POST['ID'];

I did a :

print_r($_POST); 
echo "<br>";
print_r($_GET); 
echo "<br>";
print_r($_REQUEST);

and here are the results:

Array ( [Quantity] => Array ( [0] => 0 [1] => 3 [2] => 0 ) [Order] => Array ( [0] => Ordered.2 ) [Submit] => Submit ) 
Array ( ) 
Array ( [Quantity] => Array ( [0] => 0 [1] => 3 [2] => 0 ) [Order] => Array ( [0] => Ordered.2 ) [Submit] => Submit [phpbb2mysql_data] => a:2:{s:11:\"autologinid\";s:0:\"\";s:6:\"userid\";s:1:\"2\";} )

This is just a snippet of the page, but I wanted to show the basics of what I was doing without all the other non-related code.

I appreciate the help,

Don

try

 
print_r($GLOBALS);

you should see something. If not, your html form may not correctly coded

Hi Don,

It sounds like you are expecting the $POST (and $REQUEST) variables to keep their values from the form page once you've submitted to the process page. Is that right?

To be sure, each element of the $_POST variable has to be 'sent' by a form element. Only form elements are 'posted' to the process page.

It would help if we culd see the whole form.

A rather simple question, but something in your post makes me stop and think. I may be missing the boat here, but you said you were posting from a form to another page, then the information is passed to the processing PHP page?

POST only passes variables to the next page. To move the information further onward to your processing page, you have two choices:

1) You need to create another form on the second page and require more user interaction on the second page (like clicking a button) to again POST it.

(or)

2) Parse the data onto the forwarding URL and use GET to get the information on the processing page.

Not sure if this helps or not, but I thought I'd clarify things a little bit...

Here is the code for the form(order.php) order page. This info is passed process page(process.php).

I did not include the db connection info.


$connpt = mysql_pconnect($hostname, $username, $password) or trigger_error(mysql_error(),E_USER_ERROR); 
		mysql_select_db($database, $connpt);
		$result = mysql_query("SELECT * FROM dealeritems");
		echo   "<table>"; 
		  		 echo "   <tr>".  

       "  <td width=\"100\">".'ID'."</td>"."<td width=\"100\">".'Item Name'."</td>"."<td width=\"150\">".'Item Description'."</td>"."<td width=\"150\">".'Body Copy'."</td>"."<td width=\"100\">".'Image'.
       "  </tr>";
			while ($row = mysql_fetch_assoc($result)) { 
			$ID = $row['ID']; 
			$ItemName = $row['ItemName'];
 		 echo "   <tr>".  

       "  <td width=\"100\">". 
$row['ID']."</td>". 
"<td width=\"100\">". 
$row['ItemName']."</td>". 
"<td width=\"150\">". 
$row['ItemDescription']."</td>". 
"<td width=\"150\">". 
$row['BodyCopy']."</td>". 
" <td width=\"100\"><img src =$path". 
$row['ImageName']." width=\"100\" height=\"125\"></td>". 
"<td width=\"150\">". 
"<input name=\"Order[]\" type=\"radio\" value=\"Ordered.$ID\">"."</td>". 
"<td width=\"150\">". 
"<select name=\"Quantity[]\" id=\"Quantity.$ID\"> 
<option value=\"0\">0</option> 
<option value=\"1\">1</option> 
<option value=\"2\">2</option> 
<option value=\"3\">3</option> 
<option value=\"4\">4</option> 
<option value=\"5\">5</option></select>". 
"</td>"."  </tr>";
}  

echo "</table>";
$ID = $_POST['ID'];

Here is the process page code:

$id = $_REQUEST['ID']; 
$max=100;
while($id != 0) { 
   $quantity = $_REQUEST['Quantity'];  

   $ordered = $_REQUEST['Ordered']; 
   for($i=1;$i<$max;$i++)  { 
      echo "Quantity: ".$i." Ordered: ".$ordered.$i; 
	  echo $i;
    } 
} 
echo " Thank you for your order. You will be contacted when the order is complete.";

Thanks in advance,

Don

Sorry, but I don't see no form tag what so ever in code you posted...

Is there any? If there isn't the data will not be passed to the form processing page... But I'm sure that you just didn't showed it to us...

My main question: in what form element do you have $ID? It appears to be out of any...

This:

$ID = $_POST['ID'];

...will do noting since $_POST on the form page doesn't exist unless it is passed from previous page where another form is and also it won't pass to the form processing page because it isn't in any form element...

Try:

<input type="hidden" name="ID" value="<?php echo $_POST['ID']; ?>">

This way it will be in both $POST and $REQUEST on form processing page...

But my recomendation is not to use $REQUEST at all since it can hold in $GET and $POST variable and you can't control malicious user from providing it through URL and $POST ALLWAYS holds the data posted by form...

You can see I am trying several different suggestions.

BTW, I originally had the Quantity and Ordered as a defined name and now they are a variable. This code was suggested by a user on this forum, and now once you select a product, it "de-selects" the previous product. I know there is a fix for this, also.

Thanks,

Don

I can do a:

print_r($GLOBALS);

I I do get all the info.

I did this with REQUEST GET and POST and they also return a value???

I changed my php.ini and turned on GLOBALS, and that did not make any difference.

Anyone have a clue?

Thanks,

Don

dmacman1962

This must be an un-asnwerable questions, since I got no responses.

I do not believe that there is ANY question the users of this forum cannot answer.

You people have ALWAYS had some answer.

Thanks,

Hi dmacman,

Not sure what the problem actually is, so can you do a test for me (I can't do it without access to your database).

Here's the form page (tweaked and laid out in my style so that I can see what's going on) ...

For the process page, just use this for a moment and let us know what gets displayed ...

?>

Paul :)

PS.
Here's a tip: don't use double-quotes for strings unless you absolutely have to. All that cutting in and out is impossible to debug easily. There were various errors and omissions and they were very hard to see in your layout but were obvious in mine.

Also, use the full php tags <?php ?> and not <? ?>, a lot of servers won't get the latter correct.

dmacman1962

Thanks for helping.

I am not brand new to php, but I am using it more consistently now than the past few years.

Here is the result of your code:

]

_POST:
Array
(
[Quantity] => Array
(
[0] => 0
[1] => 0
[2] => 3
)

[Order] => Array
    (
        [0] => Ordered3
    )

[ID] => 
[Submit] => Submit

)

As far as the post you asked about:

<!-- Where does this $_POST come from? --> 
<input type="hidden" name="ID" value="<? echo $_POST['ID']; ?>">

That was a suggestion another user gave to pass the results of the ID to the process.php page. Obviously, if you are asking, this is not the way to pass that variable to the next page (the process.php page).

Thanks,

Don

paulnaj

Hi Don,

So we're getting some results, but they're obviously not exactly what you want.

So, let me ask you ...

You are delivering a set of choices to the user. Is the user allowed to select more than one type of item per 'submit'?

If they are, then radio buttons aren't going to work since only one can be checked at any one time (per form) ... unless you put each one in it's own group (there's a html tag to do this).

But one radio button per radio group is just a checkbox, which might be what you want!

Paul 🙂

dmacman1962

I would like to let the user select as many items as they want.

I am trying to send the item(s) they select and the quantity.

I am glad to see you are helping me and I appreciate it.

Thanks,

Don

Hi Don,

Here's a (pared-down) version of your form and a basic response (on the same page for now) ...

Obviously, I've had to make up the ID's but see if it is doing what you want ... then we can fit it back into your original code.

Thanks Paul,

It is almost exactly what I am looking for. I can adapt the process pages as you described.

I did have one small issue, it does not pass the quantity ordered to the process page.

After looking at the order page I changes the HTML for the quantity from:

<select name=" name="quantity_<?php echo $row['ID']; ?>">

to:

<select name="quantity"[] name="quantity_<?php echo $row['ID']; ?>">

I thought that might have been the problem, but it still will not display the quantity. I noticed the options for this was html and not php, but I didn't think that would make a difference.

On the process page I added:

echo '<hr><b>_POST</b>: <pre>'; print_r($_POST); echo '</pre>';

Which give me (when I selected
item 0 Qty 5
item 1 Qty 3
item 2 Qty

HTML results below:

ID Item Quantity
1 Do Not Enter

2 Stop

3 Hello

_POST:
Array
(
[order] => Array
(
[0] => 1
[1] => 2
[2] => 3
)

[name_1] => Do Not Enter
[quantity] => Array
    (
        [0] => 5
        [1] => 3
        [2] => 1
    )

[name_2] => Stop
[name_3] => Hello
[Submit] => Submit

)

Any suggestions?

Thanks,

Don

A typo, I'm afraid ...

My line ...

... should've been ...

... and they're maybe others!!

Paul.

dmacman1962

Fantastic job Paul!!!

This is perfect.

I have read just about every post I could on this subject and spent 4 days and you solved it with about 3 replies!

Plus you code is some of the cleanest I have seen.

Thank you very much.

I am going to make a bunch of sample forms along with the real one I need to make sure this sinks in.

Have great weekend!

Don
