Problem fixed....it was upload_max_file size being set to 2mb in my php.ini......up ped it to 5mb and it works fine.
The problem wasn't with exif_imagetype it was because my $_FILES[''] values were empty....duhh! -

preg_match issues
Hi is there a specific way to check for preg_match.
Only reason i ask is im having trouble even matching basics.
I have a validation script with a function like this(for example...simpl ified for testing)
then i call it from a sepperate file such asCode:function AlphaNumeric($value){ if(preg_match("/^a-z/", $value)){ return true; } }
...Code:if(!$validation->AlphaNumeric($value){Last edited by Dormilich; Aug 31 '11, 06:31 AM. Reason: please use [CODE] [/CODE] tags when posting code -
Hi, if i was to implement this then i'd make sure i had a rollback feature aswell as a testing environment.... .its just to make things easier for me in the long run...if i had 1000 sites im sure it would get more and more difficult to keep them all updated...but thanks for the feedback.
For now ill just stick with multiple uploads.Leave a comment:

reference files from external server
Hi, im building my own CMS and wish to have my files hosted on 1 server for easy updating rather than sepperate uploads into different hosting packages etc.
My clients websites will all be hosted on different servers but i want them to access the CMS from one set of files so when i make updates they are applied to all clients.
I've tried using fopen/file_get_conten ts etc which works fine but my problems are with server... -
Not sure if I fully understand.
Are you wanting to select them all in one go and arrange the match ups then? or save some for later and select them then?
If you're matching them all up in one go can you not store the matched values in an array so when you come to create your next matchup you know who has already been selected?
or if you want to store the matched values you could store them like

Hi,
I have 2 fixed width and height textareas. with transparency and scroll bars/border hidden.
I am letting people type text into the 1st textarea....whe n they type enough text to cause the textarea to overflow/require scrolling(verti cally) i would like the focus to shift to the 2nd textarea automatically.

set text input value onclick etc
Hi,
Its something stupidly simple but for some reason i cant find a straight forward cross browser solution.
I've got 2 sets of address fields and i want a tick box that when the user clicks it populates the 2nd lot of boxes with the values in the first.
I had it working in I.E ok using the following;

PHP/MYSQL Book search

I know there are sites that offer free searches and databases to buy of the books but im not quite clever enough to do this i dont think.
Few questions then
1. Is it possible without buying a database
2. If so...how hard and does... -
Hi, i used the create statement to create the basic fields, but since then i've added a few manually, theres a user id field in my users table but its a random 32 var character, my category table doesnt yet have 1 and was created manually.
is it too late to add a primary key field in now, does it need to be done from the start.
I'm new to mysql etc so still learning a lot.
Using this method i managed to...Leave a comment:
