PHP - Help Generating A Dynamic Variable Name

hi guys I just could not find the answer on forum. I have a url like this http://www.example.com/deal.php?id=367 and my question is : how can i use curl function to get the html and the id value which is 367
thanks

I have a form that inserts information into a mysql, the only prolem is I need to add different surrounding html to the information when entering it into the database depending what the value is...(essentially I want to store font color around different levels)

How would I define the same variable with different information depending on the value?

The information is called using:

if ($_SERVER['REQUEST_METHOD'] == 'POST') {
$editLEVEL=$_POST['level'];


I want it so if 'Level1' is the posted value then $editLEVEL would be '<color=1>$editLEVEL</color>'
but if 'Level2' is the posted value the $editLEVEL would be '<color=2>$editLEVEL</color>'

If you dont understand just let me know I'll try explain best I can.

Hi !

I'd like to count all occurences in "$thiscodestring" into a "dynamic?" array and print it out after the end of the loop, how do I assign the variablenames dynamically ?

$query = "SELECT codes, status FROM table";

while ($row = mysql_fetch_assoc($result)) {
  $thiscodestring = $row[codes];  // looks like "a1 c2 d3 10 15 1 a1 a1";
  $singlecodes = explode(" ", $thiscodestring);
    foreach($singlecodes as $thiscode) {
      $$thiscode[count] = $$thiscode[count] + 1;
    }
}

After all Mysql-Stuff is done I'd like to print out the counted codes, for example the code "a1" was found 100 times in all querys then $$a1[count] should be 100, c2 was found 15 times, then $$c2[count] should be 15 and so on.

Question:
How do I tell php to assign a "dynamic" variable with the name of the found string which was exploded (in this example a1, c2, d3... ) before ?!

$$ does not seem to work.

And how can I then print_r() the value if I dont know the name ?

Thanks !

<?php 

$foo = 5; 

$too = 7;

${"foo"}++; 
${"too"}++;
echo $foo;
echo '<br />' . $too;

$my_var_name = "foo";

${$my_var_name}++;

echo $foo;
    
?>

I understand the part that $my_var_name is going to increment $foo. But I don't understand that when we used ${"foo"} we did not add the $ sign with it. But when we use ${$my_var_name} we have to add another $ sign. why is that?

Hello,

I'm working on a dynamic text form (I guess thats what its called). Basically, I have a html page that echos in some PHP code. What the PHP code does is show different strings of text depending on a variable:

Code: [Select]
<PHP?
$brief1_info = "brief info goes here";
$brief1 = 0;

if (isset($_POST['brief1Go'])) {
$brief1 = $brief1 + 1;
}
else if (isset($_POST['brief1Back'])) {
$brief1 = $brief1 - 1;
}


$breif1Controller = "
<form action=\"".$_SERVER['PHP_SELF']."\" method=\"post\">
<input type=\"submit\" name=\"brief1Back\" id=\"brief1Back\" value=\"BACK\" />
</form>

<form action=\"".$_SERVER['PHP_SELF']."\" method=\"post\">
<input type=\"submit\" name=\"brief1Go\" id=\"brief1Go\" value=\"CONTINUE\" />
</form>";



if($brief1 == 0){
$brief1_info = "<b>Welcome Commander,</b> you are currently viewing the Mission Control Brief page, here you can view all your missions that you need to complete in order to advance through your prestiges. You will need to follow your briefs carefully in order to succeed. <br /><br />

";
}
else if($brief1 == 1){
$brief1_info = "Okay, let me show you around the place ...";
}
else if($brief1 == 2){
$brief1_info = "brief is on 2";
}


?>
The problem is, the BACK and CONTINUE buttons don't work. If $brief1 equals 0, and the user presses continue, the is should go to 1, and the brief1_info string is changed (so some different text shows in my html). It actually works when brief1 is on '0', but when its on 1 and the user pressed continue, the brief1 is changed to 1, but because the submit button refreshes the page, the variable is re-read again, and thus is reset back to 0.

Is there a way around this? Or is there a better method than what I'm doing?

Thanks

Hi
I'm trying the following code:
Code: [Select]
$t = '12<-- AB_C -->';
$AB_C = 'abc';
echo preg_replace('/\<-- ([A-Z_]+) --\>/', "$$1", $t);I want to get "12abc" , but it outputs: 12$AB_C , so, it not recognize the replacement as dynamic variable.
Is it any way to use the matched word in preg_replace() as a variable, or dynamic variable?

Hi all, here's my code:

Code: [Select]
<?php
foreach ($_SESSION['topping'] as $value) {
    echo "<tr><td width='30%'>Topping</td><td width='50%'>$value</td><td width='20%'><select name='notopping'>";
foreach ($_SESSION['cupcake'] as $number) { '<option name="notoppings[]" value="'.$number.'">".$number."</option>'; }
echo "</select></td></tr>";
}
?>

$_SESSION['cupcake'] is a value from either 6, 12, 24 or 36.  What I want to do is put them into a drop down box (second foreach) as the value and the displayed value - counting up from 1 (so 1,2,3,4,5,6 or up to 12,24 etc).

Also by creating this as an array, does this mean than for each topping (say Vanilla and Chocolate) the value dynamically created can be used on the next page by using $_POST['notoppings'] to display each type (two different numbers - one for Vanilla and one for Chocolate).  Does that make sense?

Thanks!

Folks,

I need help (Php code ) to generate a Dynamic Text on a Base Image. What i want to do is, to make this Image as header on my Site and to make this Header Specific to a Site, i want to Add the Domain Name on the Lower Left of the Image.

Got the Idea?

Here is the Image link:

Quote

http://img27.imageshack.us/i/shoppingheader1.jpg/


PHP Variable that holds the Domain name is:  $domain 

All i need the Dynamic PHP Codes that i can put on all my sites to generate this Text on Image (Header) Dynamically...

May Anyone Help me with this Please?

Cheers
Natasha T.

There is a section in my site in which i will need to give the user 3 options:

Generate Specific User Text As:
            1.  pdf
            2. .doc
            3. .txt
            4. print in html

The 4th option is simple. The other three are completely new to me.

I know little bit about fopen, fwrite and fclose, however these are commands that write files to the server. I need to write files to the users computer.

Is the best way for this to be:
 1. the user clicks .txt
 2. the .txt is written to the server
 3. the .txt is then downloaded to the users computer by the user
 4. the .txt is then deleted from the server

All 4 steps to be done with one click from the user.

Might there not be traffic problems if lots and lots of users are doing this at the same time?

Any pushes in right direction here would be great, there seems to be hundreds of sites saying different solutions

Hi,

I've written some code to take information from an SQL database and write it out in the RSS format (Although it doesn't validate).

The problem is i'd like the page to have the .rss (or .xml) file extension, I'm not sure if there's any advantages in having this but thought i'd ask.

I've got the following code:

Code: [Select]
<?php 
header('Content-type: text/xml');
print '<?xml version="1.0"?>';
print '<rss version="2.0">';
        print '<channel>';
include("phpfunctions.php");
db_connect();

//select all from users table
$select="SELECT title, link, description FROM news";
$result = mysql_query($select) or die(mysql_error());

//If nothing is returned display error no records
if (mysql_num_rows($result) < 1) {
die("No records");
}

//loop through the results and write each as a new item

while ($row = mysql_fetch_assoc($result)) {
    $item_title = $row["title"];
    $item_link = $row["link"];
    $item_desc = $row["description"];

        print '<item>';
           print '<title>' . $item_title . '</title>';
            print '<link>' . $item_link . '</link>';
            print '<description>' . $item_desc . '</description>';
        print '</item>';


}
print '</channel>';
print '</rss>';

?>


This seems to work fine as i get what i expect and i'm assuming i can do the same to output .xml but is there a way to have it in a proper .rss / .xml file so that an aggregator or someone could read this properly.

Cheers,

Reece

Hi All -

I wanted to know if there is any existing script to generate an eticket when a user books a ticket through a website.

Thanks

hi guys, im trying to resize and save a thumbnail version of images uploaded to my site in a sub folder (thumbs).

I've currently got:


$image=imagecreatefromjpeg($filepath);

list($width, $height) = getimagesize($filepath);

$new_width = 200;
$new_height= 150;

$image_p=imagecreatetruecolor($new_width, $new_height);

imagecopyresampled($image_p, $image, 0, 0, 0, 0, $new_width, $new_height, $width, $height);

// Save the image
imagejpeg($image_p, '/thumbs'.$filepath);

// Free up memory
imagedestroy($image_p);


but it appears to do nothing, but it also doesn't return any errors?
could someone help me out please?
thanks!

Does anyone know of a free php library to create pdf417 2d barcodes?

As a complete newbie, I'm not sure Ive got the terminology right in my subject header. But this is what I am trying to do.

I have a soccer stats site with data entered into each of numerous 'seasons', accessible via a drop-down menu, as he
http://www.fleethistory.co.uk/stats/matches.php

Now regardless of what season I select, the URL will stay the same as above. What I want to do is have users go direct to a particular season from a link without having to use the drop-down. How would I generate a unique URL for each of the seasons listed in the drop-down?

Don't know if you need the PHP code, but here it is just in case:

I'm trying to generate a page with javascript in it with PHP.  But the quotations are causing me problems, I need a third set of quotations.  Here is the part I am having trouble with:


echo"<div class='level'>Edit:</div><div class='box'><input type = 'text'  size='50' name='cat' value='$cat'/> <b><input type='button' value='+ Details' onclick='document.getElementById('rev$clicker').style.display='block';'/></b> </div><br>";


When I view the html it comes out onclick='document.getElementById('rev$clicker').style.display='block';'

I can't use "" quotations for 'block' and 'rev$clicker' because that would exit from the echo and I can't exit php because I need the $clicker variable.
