PHP - Iptcembed -orphan Images

Ok, so first, I'm a little more experienced than a newb, but far from an expert.  And I'm fairly certain when yall help me through this I'm going to bang my head on the desk and chastize myself for not thinking of it.  So here we go.

I'm attempting to use some examples I found on php.net for the iptc embed & iptcparse functions.  What I've done is taken a class file that was posted (just a collection of the snippets), corrected it for the most part to function how it should.  It will read the IPTC data from a jpg just fine.  It'll even write to the IPTC fields.  The problem comes with the IPTC_KEYWORDS field.  That field needs to be an array and I can't get it to write properly.  Right now the only thing it's writing is the word "array".

Also, I'm a bit confused as to what one of the functions is trying to do and I think it's the function that's causing the mess.  Below are the classfile and then the test file making the call.

And here's the test-call: Code: [Select]
<?php
require_once("iptceasy.php");

$i = new iptc("fortworden.jpg");
$keywords = array( "keywords" => "updatedkey1", "updatedkey2", "updatedkey3" , "updatedkey4" );
echo $i->set(IPTC_KEYWORDS, $keywords);
$i->write();
echo 'Done.';
?>
If I try to set any of the other IPTC fields with a string, the functions work fine.  I'm fairly certain the error is either in the set() function or the iptc_maketag() function.  And the iptc_maketag() function is the one I'm stumped about.  Is that binary that it's prepending to the data?

Thanks for any light you can shed and help you can give on this in advance!

Hello 

(I think this is more of a php question than MySQL - sorry if I have got it wrong.)

I need to know if items have been orphaned (because they lack a cat_id that actually exists).


I have two MySQL tables that each have fields 'cat_id'.

I have a Category table...

cat_id / category
1 / fruit
2 / veg
3 / tools


I have another product table
 
cat_id / product
1 / apple
1 / Pear
2 / carrot
2 / cabbage
3 / screwdriver
1 / peach
8 / orphan

I have entered the data into two arrays...

$categories[]
$products[]

I have tried a number of combinations of foreach loops to try to determine if the products(cat_id) doesn't match the categories(cat_id) but I seem to be going around in circles.

Is there perhaps a function that is available to do this?

Or maybe just a straight thinking person that can point out my ineptitude?

Thank you for any input.

I have this script from http://lampload.com/...,view.download/ (I am not using a database) I can upload images fine, I can view files, but I want to delete them. When I press the delete button, nothing happens   http://www.jayg.co.u...oad_gallery.php   <form> <?php $dir = dirname(__FILENAME__)."/images/gallery" ; $files1 = scandir($dir); foreach($files1 as $file){ if(strlen($file) >=3){ $foil = strstr($file, 'jpg'); // As of PHP 5.3.0 $foil = $file; $pos = strpos($file, 'css'); if ($foil==true){ echo '<input type="checkbox" name="filenames[]" value="'.$foil.'" />'; echo "<img width='130' height='38' src='images/gallery/$file' /><br/>"; // for live host //echo "<img width='130' height='38' src='/ABOOK/SORTING/gallery-dynamic/images/gallery/ $file' /><br/>"; } } }?> <input type="submit" name="mysubmit2" value="Delete"> </form>   any ideas please?   thanks

Hey every i'm just trying to change my 'Read More' text after a blog post on my site into am image. Got some code that lets me change the actual text to something else, just can't find how to change the text into an image.

Code: [Select]
add_filter( 'the_content_more_link', 'child_content_more_link', 10, 2 );
function child_content_more_link( $more_link, $more_link_text ) {

    return str_replace( $more_link_text, 'my new read more text', $more_link );

} 

Thanks,

Hi guys

I just want to know something. With php you can handle excel files by saving them as .csv files. Then the php script reads it line by line, and commas separating the fields. But is it possible that I can insert an image (small jpg or png) file in one of these fields...and then handle the image in the php script?

Just for intrest I inserted an image in excel worksheet and it did not insert it into a cell, it float. Is there maybe another to insert it in the cell and then control it with php??

Thanx in advance
