PHP - Trying To Change Inline Image Conditionally In An Array...help

I've figured out how to change all of an arrays keys to lowercase:


 $lower_case_array = array_change_key_case($mixed_array, CASE_LOWER); 



But I can't seem to find a way to change the values of an array to lower case. Is there a simple way to do this?

I am echoing a variable that is an array.  I want to change the first part of the variable but don't know how to manipulte names inside the ['brackets']
Code: [Select]

echo $row['v1_name']);?>



lets say I have a value called $var = v1.  How do I substitute that like this:
Code: [Select]
echo $row[$var.'_name']);?>
I know the above doesnt work, but thats what i want it to do :-)

Hello,

I'm a new  building my career as a web developer/designer and i'm attempting to create an array that holds different attributes of all the web projects.

Site1 => array('www.siteurl.com','hostAccountName','Offline domain name',) ,
Site2 => array('www.site2url.com','hostAccoun2tName','Offline domain2 name') ,
Site3 => array('www.site2url.com','hostAccount3Name','Offline domain3 name') ,

 I have many sites in the multidimensional array BUT each has the same format of attributes. I store this entire array in one file that gets included, and based on some logic later , the script will decide which site i'm currently working on and thus that site's attributes must be used, since i will just use one variable where these attributes are needed and leave it upto some logic to decide which site's attributes to use.


Objective of the code : To change the array keys of each site's attributes from 0,1,2 etc to more readable strings for later use to directly access values. I'm creating an array with the values first and then running some code to change the keys later because i might decide to change the key names later and i can't manually edit it for each of the array values because the array might grow much larger.

Site1 => array ([0] => 'www.siteurl.com',
                          [1] => 'username@hostserver',
                          [2] => 'siteOfflineDomain');

must change into

Site1 => array (['siteUrl] => 'www.siteurl.com',
                          ['hostingUserName'] => 'username@hostserver',
                          ['OfflineVirtualHost'] => 'siteOfflineDomain');

And this must happen in a foreach loop and go through all the sites to change all the default 0,1,2 indices, to the index names i provide.


Code :

$siteList = array (
'site1'     => array
(
'www.site1.com',
'site1@host',
'site1_offline'
      ),
  
'site2' => array 
(
'www.site2.com',
'site2@host',
'site2_offline'

),

'site3'  => array
(
'www.site3.com',
'site3@host',
'uttarkar_offline'
)   
);



foreach ($siteList as $sitePrefix => $siteAttributes) {
foreach ($siteAttributes as $oldIndex => $attribute) {
switch ($oldIndex) {
case 0 :
$siteAttributes['siteUrl'] = $siteAttributes[$oldIndex];
unset($siteAttributes[$oldIndex]);
break;
case 1 :
$siteAttributes['hostserverUserName'] = $siteAttributes[$oldIndex];
unset($siteAttributes[$oldIndex]);
break;
case 2 :
$siteAttributes['offlineDomainName'] = $siteAttributes[$oldIndex];
unset($siteAttributes[$oldIndex]);
break;
}
}

echo 'The newly edited attributes array for ',$sitePrefix,'is '.print_r($siteAttributes),'<br><br>';
}


Problem : This script works great, and the indices for the attributes get changed as expected, as you will see in the echo statement. But if i do a echo $siteList['site1']['siteUrl'] after the code, it says 'unknown index siteUrl'. Then i check the entire array with print_r($siteList) , and all the index keys are back to being 0,1,2!. My guess is that theres something i'm missing here to make them stick, but i spent 3 hours trying to figure it out, and i was getting a bit impatient, so can i get some help on this one please , thanks.

Using php I have a dynamically filled select box with the names of images. How can I get an image box on my page and change upon selection?

Hi all,

I am dealing with an html page in which a dynamically created PNG image is shown with:

<img src="createchart.php">

The problem arises when users try to download the image since the default name that appears is just "createchart.php".
Is there any way to make the browser suggest something like "chart.png"?

Than you guys for your help,
Mam

This creates an image 1500x1500 pixels. But it creates it in black... how can i make it white.
And i have to use imagecreatetruecolor() not imagecreate().


<?php

$im = imagecreatetruecolor(1500,1500);


// Output the image to the browser
header('Content-type: image/jpg');

imagejpeg($im);
imagedestroy($im);
?>


Thanks!

Main URL of website home page:  www.mysite.com  and this shows image "A" in the header.

I want to have a marketing campaign which will send people to my site via this link:  www.mysite.com/index.php?ref=att

When people get to my site via the 2nd link, I want to show image "B" instead of image "A".

I put this at top of home page...

Code: [Select]
require_once("includes/session.php");
if (isset($_GET['ref']) && ($_GET['ref'] == "att")) {
$_SESSION['ref'] = "att";
} else {

}
and this code is in my header include file, a little further down on the page...

Code: [Select]
<?php

if (isset($_SESSION['ref']) && $_SESSION['ref'] == "att") {
echo "<span class='phone'><img src='/images/B.png' /></span>";
} else {
echo "<span class='phone'><img src='/images/A.png' /></span>";
}
?>
Does this look right?  because I can't get it to work.  It's showing image A regardless of which URL I use.  I have to be missing something obvious because I really thought this would be super easy to do.

If anyone sees any problems, let me know. But I'll keep testing and hopefully find my mistake.

Thanks!

i am new to web designing,   i don't know much about javascript.   <select id="plan" align="center" valign="center">

I have a PHP script that uploads images to a folder on my server (attachments folder). Currently the folder sits within my webroot and is publicly accessible (I have to use chmod 777 due to permissions issue). So, I created the "attachments" folder outside of my webroot (so that it is not publicly accessible), but I do not know how to set the path in the PHP code to upload it to that "attachments" folder outside of the webroot. As you see in the snippet of PHP code below, the code currently uploads the the "attachments" folder within the www (webroot) directory. How do I make it upload to the "attachments" folder OUTSIDE of the www (webroot) directory?

foreach($files[$form] as $file){
         $str = $file[1];
         if (eval("if($str){return true;}")) {
            $_values[$file[0]] = $_FILES[$file[0]]["name"];
            $dirs = explode("/","attachments//");
            $cur_dir =".";
            foreach($dirs as $dir){
            $cur_dir = $cur_dir."/".$dir;
            if (!@opendir($cur_dir)) { mkdir($cur_dir, 0777);}}
            $_values[$file[0]."_real-name"] = "attachments/".date("YmdHis")."_".$_FILES[$file[0]]["name"]."_secure";
            copy($_FILES[$file[0]]["tmp_name"],$_values[$file[0]."_real-name"]);
            @unlink($_FILES[$file[0]]["tmp_name"]);
         }else{
          $flag=true;
          if ($_isdisplay) {
              //$ExtFltr = $file[2];
              //$FileSize = $file[4];
            if (!eval("if($file[2]){return true;}")){echo $file[3];}
            if (!eval("if($file[4]){return true;}")){echo $file[5];}
              $_ErrorList[] = $file[0];
          }
         }

Hey guys!
I have the following php code that grabs variables (and the browsed image) from Flash.


//FLASH VARIABLES
$Name = $_POST['Name'];
$itemNumber = $_POST['itemNumber'];
$filename = $_FILES['Filedata']['name'];
$filetmpname = $_FILES['Filedata']['tmp_name'];
$fileType = $_FILES["Filedata"]["type"];
$fileSizeMB = ($_FILES["Filedata"]["size"] / 1024 / 1000);


list($filename, $extension) = explode('.', basename($_FILES['Filedata']['name']));
$filename = $Name;
$target = $filename . $itemNumber . "." . $extension;


// Place file on server, into the images folder
move_uploaded_file($_FILES['Filedata']['tmp_name'], "images/".$target);



This works perfect, but what I want to change is the width and height of the uploaded image.
Any ideas/suggestions on how this could be done?

Thanks in advance!!
Cheers!

Hi, I have a game image gallery using arrays to hold the current images, and when you go to a new location, like "newLocation=2" , it goes to a new array of background images. The problem is, when I try it in my browser, and I put in a new array of image for like, "location 2", The image doesn't show up, the images from location 1 show up. This is driving me nuts because I want to start adding content to the zones of my game already.LOL!. If anyone can help please I'd be very grateful. Thank you. Derek

ok, here is the code to the page, I only included the parts of the page that are relevant to what I am talking about.

Code: [Select]
<?php

session_start();

$echoLocation='';
$player='';
$monsters='';
$_SESSION['player'] = $player;// set this right after they log in, run this once, eventually in database.
$_SESSION['monsters']=$monsters;

$currentMonsterLevel='';//get rid of this eventually and put in session variable cuz we use it on other pages.
$currentPlayerLevel='';
$error='';
