PHP - A $_post['titel[$n]'] Problem

I'm trying firstly to output hidden fields based on the values of the $_POST variable.

Then after that I want to output the values again in a unordered list.

I'm using the following code:
while (list($key, $val) = each($_POST)) {
if ($key != 'Submit') {
echo '<input type="hidden" name="' . $key . '" value="' . $val . '" />';
}
}

echo '<ul>';
while (list($key, $val) = each($_POST)) {
if ($key != 'Submit') {
echo '<li><strong>' . $key . '</strong>: <span class="highlight-219ddb">' . $val . '</span></li>';
}
}
echo '</ul>';

However the <ul> appears to be blank? Can I only use the list() function once on a particular variable?

I have a problem that occurred only recently, apparently by some change my webhost made on the server.
Some time ago I wrote a script that simulates a Poedit-type editor. The script has about 1500 textareas (the translation fields) with unique names, dynamically generated.
All worked fine. Now suddenly I get errors (see below) when I use more than 1000 textareas. It is not a problem of $_POST size, if happens also with empty textareas.
I will show here a simple php test file that I called testta.php, which creates the same error as my much more complicated real script:
 
Code: [Select]
<?php
if(isset($_POST['test'])) {
    echo 'The textareas were posted successfully!<br>';
}
$max = 1500;
echo '<form action="testta.php" method="POST">';
echo '<input type="submit" name="test" value="Submit"><br>';
for($i=0; $i < $max; $i++) {
    echo '<textarea name="test'.$i.'">name is test'.$i.'</textarea><br>';
}
echo '</form>';
?>
The error message generated in the browser:
500 Server Error: A misconfiguration on the server caused a hiccup. Check the server logs, fix the problem, then try again.

From the Apache log file:
[Sat Apr 28 12:47:48 2012] [error] [client 93.172.175.50] Premature end of script headers: testta.php, referer: http://****/*****/testta.php 
(stars added for privacy)

When $max is set to a number < 1000 it works.
On the web I have only found answers that deal with max size of posts, but as I mentioned that is not my case.
My webhost can't help me out either. Until last Friday all worked fine.
Does anyone know what server setting could create this problem?

Thanks in advance,
Kathy

Hello,

My script here is not sending POST vars from form to script. I can't figure it out.

Hi guys, running through this tutorial at the moment:

http://www.tizag.com/phpT/forms.php

I seem to keep having problems with the $_POST variable. Is that obsolete syntax now?

Here's the part I get an error on:

<html>
<body>
<?php
$quantity=$_POST['quantity'];
$item=$_POST['item'];

echo "You ordered".$quantity."".$item.".<br/>.";
echo "Thank you for ordering from Boombaby art supppplies!";

?>
</body>
</html>


Here's the error:


( ! ) Notice: Undefined index: quantity in C:\wamp\www\process.php on line 4
Call Stack
#   Time   Memory   Function   Location
1   0.0009   363936   {main}( )   ..\process.php:0

You ordered.
.Thank you for ordering from Boombaby art supppplies!



Any help would be appreciated. I tried googling but everything didn't seem to answer my question or was too confusing.

Thanks.

Hi guys,

I have a form using radio buttons.
For the radio button, lets just say i have the id name as 'rim' + number eg; rim0, rim1, rim2....

When i post the data to another file to execute the data collected, naturally i would use the:
Code: [Select]
$rim0=$_POST['rim0'];
$rim1=$_POST['rim1'];
....
$rim10=$_POST['rim10'];
i tried to shorten this process using this method:
Code: [Select]
//$q is part of the post variable.
for($x = 0; $x < count($q); $x++){

$rim[]=$_POST['"rim"."$x"'];
}
But i get this error
Code: [Select]
Notice: Undefined index: "rim"."$x" in D:\Apache Software Foundation\Apache2.2\htdocs\.....\#####.php on line 20
Notice: Undefined index: "rim"."$x" in D:\Apache Software Foundation\Apache2.2\htdocs\.....\#####.php on line 20

Is there something wrong with my POST syntax?

I use a form to sent date and  use php to display it . However , the code only can working on one page. I can not turn the page. I do not why . Please tell me reason . Thank you very much.

<select name="kind">
  <option >kind</option>
 <option value="Copier Toner">Copier Toner</option>
        <option value="Laser Toner">Laser Toner</option>
      <option value="MICR Toner">MICR Toner</option>
      <option value="Inkjet">Inkjet</option>

$rs_result = mysql_query($sql,$connection);
$row = mysql_fetch_row($rs_result);
$total_records = $row[0];
$total_pages = ceil($total_records / 18);
 
for ($i=1; $i<=$total_pages; $i++) {



?>


      <div class="trunpage"><a href='table2.php?page=<?php echo  "$i" ; ?>&id=<?php echo "$_POST[brand]";?>&cd=<?php echo "$_POST[kind]";?>&td=<?php echo "$_POST[type]";?>'  ><?php echo  "$i" ; ?></a>

The first page is working fine. The second page I get error message.

Undefined index: brand in C:\wamp\www\php1000\table2.php on line 234

Here's the result of my problem:
Array ( [nav_create_title] => hel [nav_visible] => 1 [category_position] => 4 )

Here's how I'm trying to assign and echo $_post.
print_r($_POST);
$category_pos = $_POST["category_postion"];
$nav_title=$_POST["nav_create_title"];
$nav_visible=$_POST["nav_visible"];



echo $nav_title;
echo $category_pos;
echo $nav_visible;


As you can see, it prints the correct value and name from the array... why the heck can't I assign or echo it?

Here is how I am sending it from the other page in a form (it used to be simple, but I've been trying every work around i can think of:
<?php
$result=mysql_query("SELECT * FROM category WHERE visible='1' ORDER BY position ASC");
$row=mysql_fetch_array($result);
$positionID=$row['position'];
$position=$row['position'];

$selectname .= "<select name=";
$selectname .= "'category_position'";
$selectname .= ">";
echo $selectname;
$rownumber=mysql_num_rows($result);
$rownumber_temp=$rownumber+1;
For($i=1; $i<=$rownumber_temp; $i++)

}

$selectname2 .= "echo \"<br />\"";
$selectname2 .= "echo \"</select>";
echo $selectname2;

I have a code designed to build buildings on space colonies.
The problem is that once you click the form button, the building is built, but you need to reload the page before it will show the updated count.
Is there a way to refresh a page so that the change shows up without the user doing anything?

Running into some problems with my code.  I am having the user search the Database with either a UAID or the user's full name.  It works fine when you input both the UAID and name; however, I want it to work if only one is give (i.e. just the name or just the UAID).

I decided to use the isset($_POST) function of php but I am not getting it to work correctly.  PHP believe it is set even though it is empty.

Here is my html form.

Is there an easy way to dump out the contents of a $_POST array and display them on my screen?

(I'm trying to get more comfortable with what is stored in the $_POST array and how it is structured.)

Thanks,

Is it possible to redefine a $_POST after PHP has received the value of it via a HTML form?
Something like this:


if ($_POST['category'] == "Belts") {
        $_POST['category'] = "belts";
}

Hi guys i am a PHP newbie trying to learn from the beginning. I am reading a php book and i can't get past a particular example because $_GET and $_POST just won't work. Below is the code i am working with:

HTML File
<form action="welcome1.php" method="get">
    <div>
     <label for="firstname">First name: <input type="text" name"firstname"
      id="firstname"/></label>
    </div>
    <div>
        <label for="lastname">
            Last name: <input type="text" name="lastname" id="lastname"/>
        </label>
    </div>
    <div>
        <input type="submit" value="GO" />
    </div>

PHP file

<?php
 $firstname = $_GET['firstname'];
 $lastname = $_GET['lastname'];
 print 'Welcome to our website, ' .
    htmlspecialchars($firstname, ENT_QUOTES, 'UTF-8') . ' ' .
    htmlspecialchars($lastname, ENT_QUOTES, 'UTF-8') . '!';
?>

I am working on a windows pc with Vista home edition installed. I run a localhost server installed via XAMMP. Please this has been a recurring problem for me. Each time i get to this stage in the past i always get stuck. $_GET and $_POST just does not work for me. Please heeeelp!

This is what I have for code:
Code: [Select]

How come $_POST['email'] isn't getting passed down the steps? I have a hidden field that holds it in each step... what am I overlooking?
