[Resolved] Recalling images without knowing name?

[OmegaZero]

Okay, the subject might be a bit confusing. Basically, so far i've got a script thingy that allows it to read all files within a specified folder.. From there it then selects all with *.jpg... Problem is i need to select only a range of these pictures. Let's say thiers 99 pictures total. They're Numbered 1-99 (no 0 on front of the pictures). The user inputs 3, and it gets 3-11 (9 pictures). It always gets 9 - thats the magic number here heh. Okay! so! here's what i have so far:

<?php

$numhigh = $numlow + 8;

function numCount () {
for ( ; $numlow < $numhigh; $numlow++ ){}
			}

if ($handle = opendir('.')) {
   while (false !== ($file = readdir($handle))) { 
       if ( ereg("numCount(.*).jpg", $file) ) { 
		for ( ; $numlow < $numhigh; $numlow++ )
		{
			print ("<img src='");
			echo ($numlow);
			echo ($file);
			print (".jpg'>");
		}
		}          

       } 
   }
   closedir($handle); 
?>

$numlow is specified via a form.. and yes, i know its very sloppy. hint hint: noob forum 😛 a friend helped me with parts of it, but unfortunately, he hasnt been around much and even if he is he's very busy.. and also, i know the code repeats itself, but the thing is, i just dont understand how to get it to see $numlow*.jpg. 😐 I guess i could just rename all the files, but that'd be a pain in the butt 😛 After i get that done, I want to be able to make it loop over a text doc too.. but im not going to worry about that yet.

Hi,

are these pictures are all named exactly 1.jpg, 2.jpg, ... or can they have any name ? Do you want to have any kind of sorting ?

You need to put the files into an array and loop through that.

if ($handle = opendir('.')) {
    $files = array();
    while (false !== ($file = readdir($handle))) { 
        if ( ereg("numCount(.*).jpg", $file) ) { 
            $files[] = $file;
        }
    }
}

Then you can just call the images from your $files array.

for($i = $numlow; $i < numlow + 8; $i++) {
    echo $files[$i];
}

I'm still pretty new to php myself and someone else may have a better way of doing this, but that's the basic idea.

ah i think i didnt explain myself enough.. it recalls 9 pictures at a TIME. I have 1-96 picture wise. The file names are formatted as, for example, 11ODonnell.jpg... its hard 😐 anyway i got a hold of my friend and we fixed it up a bit :p

Edit: Order DOES in fact matter :/ from lowest to highest..

$numhigh = $numlow + 8;

if ($handle = opendir('.')) {
   while (false !== ($file = readdir($handle))) { 
if ( ereg("([0-9]+)([a-zA-Z_-]*)\.(jpg|gif)", $file) )
{
	for ( ; $numlow <= $numhigh; $numlow++ )
		{
			print ("<img src='");
			print ("$file");
			print ("' width=200px height=200px>");
		}
		}          

       } 
   }
   closedir($handle);

Do you have PHP 4 (or has the script to be PHP 4 compatible) or PHP 5 ?

[OmegaZero]

its version 4.3.8 of PHP... I just decided to change all the friggin file names 😛 SO NOW! I need to make both a .txt file and jpg insert.. here's my code (the script times out and crashes the comp o_o)

<?php

$numhigh = $numlow + 8;
$tdcountA = 0;
$tdcountB = 0;
$tdcountC = 0;

if ($handle = opendir('.')) {
   while (false !== ($file = readdir($handle))) { 
			if ( $tdcountA == 0 ) {
			echo ("<tr>");
						}
		for ( ; $numlow <= $numhigh; $numlow++ )
			{
				$tdcountA++;
				echo ("<td>");
				print ("<img src='");
				echo ($numlow);
				print (".jpg' width=210px height=155px>");
				echo ("</td>");
				if ( $tdcountA == 3 ) {
					echo ("</tr>");
					$tdcountA = 0;
					$tdcountB++;
							}
				if ( $tdcountB = 1 ) {
					echo ("<tr>");

				for ( ; $numlow <= $numhigh; ) {
				$tdcountC++;
				echo ("<td>");
				include ('$numlow.txt');
				echo ("</td>");
				if ( $tdcountC == 3 ) {
					echo ("</tr>");
					$tdcountB = 0;
					$tdcountC = 0;
							}
						}
								}
		}
		}
	}
   closedir($handle); 
?>

Help much? :S

Hi,

this line
for ( ; $numlow <= $numhigh; ) {
causes an infinite loop. You code looks a little bit messy so how do you want to display the 9 images (table structure) and what does the textfile contain ?

ah well... once again ive changed this, considering i needed to do a way I KNEW would work heh. So, the description area part thingy will be done through mysql.. which is easy enough for me..i already have it coded just need to change some simple vars.. ANYWAY i wanted 9 rows and 3 columns.

Picture Picture Picture
Text Text Text
Picture Picture Picture
Text Text Text
Picture Picture Picture
Text Text Text

Get me? good. Hmm good toknow about that loop.. that would be why my script freaked out haha... well i suppose thats it o_O
