Dynamic PHP question

[Leprakawn]

Hey, all... time for a new question!!

Okay, I googled this not really knowing what to call it, so my results were not successful; however, hopefully someone here can grasp the concept and let me know if this is possible.

[- Page-of-images.php -] Contains links to images

[- single-page.php -] view any/all imgs here

Is there a way to make a list of pictures on one page, and then have the pictures open on another page, which means that page be coded some way to view the requested picture?

I know about targeting to the window name, but I am curious to see if I can make a single page open imgs dynamically.

Here is a free sheep to the first person who can successfully answer this question!

YES!

Are you talking about haveing the link target the same page to open all images in?

Yeah, I want to code a single page for the imgs to open in vs. having to code a bunch of pages showing the imgs. I am trying to save some time here.

It's pretty simple really. You'll want to play a bit with query strings (the $_GET global variables) to make the page do what you want, depending on what information you feed it.

If I'm understanding what you're asking, you would want to create a function something like the following, and then call it within your "pageofimages.php" file:

PHP Code:

<?php
function showlist() {
    echo '<ul>\n\r';
    $myimgs = array('pic1.jpg'=>'Picture 1','pic2.jpg'=>'Picture 2','pic3.jpg'=>'Picture 3','pic4.jpg'=>'Picture 4');
    foreach $myimgs as $imgname=>$imgdesc {
        echo '\t<li><a href="picviewer.php?picname='.$imgname.'">'.$imgdesc.'</a>\n\r';
    }
    echo '</ul>';
}
?>

Then, the code within picviewer.php (your "single-page") would look something like:

PHP Code:

<?php
if(!empty($_GET['picname'])) {
?>
<img src="<?php echo $_GET['picname'];?>" />
<?php
}
else {
?>
There is no image to show
<?php
}
?>

Hmm, after looking at your example, I am not exactly sure how I would combine the page o' pictures code with what I already have. Here is one example:

<a class="menu" href="javascript:windowHandle = window.open('imgs/food/chickenrollatiniwfs.jpg','img','top=0,left=0,width=540,height=295'); windowHandle.focus()" onmouseout="window.status=' '" onmouseover="this.T_BORDERCOLOR='#C4C7BE';this.T_WIDTH=156;this.T_BGCOLOR='#ffffff';this.T_OFFSETY=-7;this.T_FONTSIZE='9px';this.T_SHADOWCOLOR='#636363';this.T_SHADOWWIDTH=4;return escape('<img src=\'imgs/food/chickenrollatiniwfs-sm.jpg\' width=\'150\'> Click to zoom.')">

When the visitor drags over the item, a small preview is available, and when it is clicked, a larger view appears.

What I am shooting for is a larger view with some extra stuff added around the img, but I do not want to have to create all of the extra pages per item, which at this moment is about 130'ish imgs.

Your links should look something like:

<a class="menu" href="javascript:windowHandle = window.open('picviewer.php?pic=imgs/food/chickenrollatiniwfs.jpg','img','top=0,left=0,width=540,height=295'); windowHandle.focus()" onmouseout="window.status=' '" onmouseover="this.T_BORDERCOLOR='#C4C7BE';this.T_WIDTH=156;this.T_BGCOLOR='#ffffff';this.T_OFFSETY=-7;this.T_FONTSIZE='9px';this.T_SHADOWCOLOR='#636363';this.T_SHADOWWIDTH=4;return escape('<img src=\'imgs/food/chickenrollatiniwfs-sm.jpg\' width=\'150\'> Click to zoom.')">

Then, picviewer's code would look like:

PHP Code:

<?php
if(!empty($_GET['pic'])) {
$imgsrc=$_GET['pic'];
}
?>
<img src="<?php echo $imgsrc; ?>" />

Curtiss, I have not tested this yet, but you totally rock!!!

[curtiss]

I hope it works for you.

If you really want to get fancy, you could store the locations of your images inside a database or an XML file, and then you could pull a description, etc. from the database/XML file to show on the page with your image. It wouldn't take much more coding, it would just take a bit of work to get the images and their descriptions, etc. into the DB or XML file.

...completely over my head, but thanks for the info. If I ever need to figure that out, I know who to ask!

And yes, the code you sent works. You are a lifesaver!!!
