Problems With Writing $_post To Xml	View Content

I posted a question on this topic, but didn't receive any replies, but my question has evolved since...

I have a massive form sending post data to a page that I want to write the values to an XML below is an example of an echo that I did in the format of:

E07_37_1 - 1
E07_37_2 - 1

Should be written in the XML, similar to:

<E07_37>Data</E07_37>
<E07_37>Data</E07_37>

Many all of the elements will be embedded in a parent node to one level or another (some of them can get pretty deep) ie:
Code: [Select]
<...>
<E07>
<E07_37_0>
<E07_37>Data</E07_37>
...For this I have a switch statement to determine what parent elements the given element belongs to ie:
        switch ($row){
         ...
        case "E07_03":
        case "E07_04":
        case "E07_09":
        case "E07_10":
        case "E07_14":
            $cursub = $curblk."_03_0";
            $xml->Header->Record->$curblk->$cursub[$multi]->$row = $value;
            break;
I'm writing to the XML like so:
$dom = new DOMDocument('1.0');
$dom->preserveWhiteSpace = false;
$dom->formatOutput = true;
$dom->loadXML($xml->asXML());
file_put_contents('output.xml', $dom->saveXML());

So, I have thought much of that stuff through, and I thought I was on the right track but from what I can tell, the values in $xml aren't updating (from the existing value to the new value) nor new elements aren't being added. The only thing that is changing from the old XML to the new is it's adding a random (and unwanted) element at the end of each <E##> parent block: <E>value of last element in parent structure</E> and some times <0>blah</0>.

So I'm pretty much completely lost now and feel like most of what I've done is a complete waste of time. Someone please help! I'm sorry if my explanation is long and hard to understand but I figured it would be better than posting 300+ lines of code - So instead I attached it...

Any help is greatly appreciated...

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?

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

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?

$_post Variables

Similar Tutorials

Ok- I have seen it go both ways on this forum and I was wondering which is correct- or more secure.

I have a script that receives $_POST variables from a form. Which is better- to change the name of the $_POST variable to do script manipulations or to simple do them with the $_POST['whatever']

$whatever = $_POST['var_from_form'];

or simply utilize $_POST['var_from_form']

I know it would be less typing changing it to $whatever, but does it really matter?

And yes- register_globals is off.

How To See What Is In $_post Array?

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.)

Is It Safe To Use $_post For This?

Similar Tutorials

I have a button that uses $_POST to send information to another page. The data is in a hidden input so it's not possible for users to change information. I have nothing to check if the data is correct on the other page. Is it still possible for people to change the $_POST data though? Or somehow send false $_POST data to the other page?

$_post Problem

Hi, I am using POST to send the id of a row in a MySQL database, this id should then be used to delete the row from MySQL, this all works fine when I use GET, but as soon as i try and use POST (for security reasons) it deletes another row.
Here is the code ($_POST):
Code: [Select]
<?php

$member = $logged['username'];
//IFMESSAGES THEN SAY OTHERWISE SAY NO

$seemessages = mysql_query("SELECT * FROM `rmail` WHERE `to` = '$member' && `status` = 'unread'");
$howmanymessages = mysql_num_rows($seemessages);

$seereadmessages = mysql_query("SELECT * FROM `rmail` WHERE `status` = 'read' && `to` = '$member'");
$howmanyreadmessages = mysql_num_rows($seereadmessages);
$totalmessages = $howmanyreadmessages + $howmanymessages;
//MENU FOR USING EMAIL VIEWED ON ALL SECTIONS OF R-MAIL
echo'<div id="emailmenu"><a href="rmail.php">Home</a>|<a href="rmail.php?inbox">Inbox('.$howmanymessages.'/'.$totalmessages.')</a>|<a href="rmail.php?compose">Compose</a>| </div><br/>';

if(isset($_POST['delete'])){
//DELETE MESSAGE
$id = $_POST['delete'];
echo $id;
$newvalue = mysql_query("SELECT * FROM data");
$newvalue = mysql_fetch_array($newvalue);
$newvalue = $newvalue['rmailsent'];
$newvalue = $newvalue-1;
mysql_query("UPDATE data SET rmailsent = '$newvalue'");
mysql_query("DELETE FROM rmail WHERE `id` = '$id'");
echo "Message has been deleted!";
}
else if(isset($_GET['inbox'])){
$username = $logged['username'];
//DISPLAY EMAILS FOR USER
//WHEN DISPLAYING DISPLAY LINK WITH THE ID TO VIEW THE SPECIFIC MESSAGE
$getemail = mysql_query("SELECT * from rmail WHERE `to` = '$username' ORDER BY `id` DESC");

echo'

Using $_get And $_post

Similar Tutorials

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!

Link $_post ?

Similar Tutorials

Hey,

I have a database with user info in it. I was wondering would it be possible to have a link post info to a page and then have that page display info relevant to the received info?...

Link page:
<a href="profile.php?name=<? print $_GET['Username'] ?>" method="post"><? $row['Username'] ?></a>

Profile page:

<?php
$username = $_POST['Username'];
$query = $query = mysql_query('SELECT * FROM users WHERE Username')
?>
You are viewing: <? echo $username ?>'s profile.

Email: <? echo $row['Email'] ?>

I have predefined $row.

Is it possible to do this way or would I have to use a different method?...

Cheers

Can Not Get $_post, Even Though I Can Print_r It

Similar Tutorials

Here's the result of my problem:
Array ( [nav_create_title] => hel [nav_visible] => 1 [category_position] => 4 )
( ! ) Notice: Undefined index: category_postion in C:\wamp\www\tryitandbuyit\includes\category_create_process.php on line 7
Call Stack
# Time Memory Function Location
1 0.0010 370336 {main}( ) ..\category_create_process.php:0

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 A Position:<br />";
$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++)
{
echo "<option value= $i>" . $i . "</option></br>";

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