a trickyt one!

Anon

hi again,
ok, this is bit too tricky for me, and i cant get around this problem at all.

I have a textarea type in the form, where user can enter large text. inside the text i can have something like this:
[image]1[/image]

now, i want to take the value inside the tags, and process that against db, and get that particlur image ID's path, filename, x & y etc.

i thought of regex(), but i can only then replace the [image] and [/image]. I cant catch the middle text, to process it, and then replace the whole lot with normal <IMG ...> tag.

so, the problem bit is to get the value in between, and then to replace the whole thing.

thanks for reading, i hope anyone there can come up with something.

regards,
Daarius ...

I\'d be interested in what the \"correct\" way to do this is, as I ran into the same problem. What I ended up doing was to use the same delimiter on both sides of the value (say something like [image]1[image].) Then you can explode(\"[image]\",$textarea) (see explode in the manual) into an array. If there is just one [image]1[image] string in the text area, then $textarea_array[1] will contain that value. If there are multiple images in the text area, the values will be in every other position in the array (every odd valued key -> 1,3,5,7...) Even if the text area starts with [image]1[image] this will still work, as the $textarea_array[0] will just be null and [1] will have the image id. After you grab all your ids out of the odd numberd keys in the array you can sub the appropriate html img code for the image ids and implode the whole array (using \"\" as the glue) to get the textarea back into a single string. Probably there is a more elegant way to do this. Anyone? Mine works at least. Let me know if it is not clear and I\'ll try to explain again. Good luck.

Very basic:

$img = ereg_replace("[image](.*)[/image]", "\1", $str);

but that will replace the whole thing without giving ME any value that was in between those 2 tags. I need the integer between the tags, so that i can process that value against db, and then replace with the appropriate string.

hi,
i have solved it myself, in only 3 lines of code!

original string something like:
$string = 'blah blah .. [image]001[/image] ..';

$patern1 = '[image][0-9]{1,}';
$patern2 = '[\/image]';

$search_for_id = ereg($patern1, $string, $arr_id);

// arr_id[0] will carry the matched string i.e. [image]001

// this will chop off the first 7 characters i.e. [image]
$the_id = strsub($arr[0], 7);

so now $the_id = 001

thats it! you can now use the $the_id to do whatever you want.

and after this you can replace the whole [image]001 with the generated code, e.g:

$new_code = ereg_replace($patern1, $generated_code, $string);

I hope this is useful for you too Jim.

Which is what it would have given you, depending on the circumstances. Like I said - my answer was "very basic". To get an exact answer, you need to give your exact requirements. How many digits will be between the two tags?; will always be digits?; how many times will the string occur?; etc.

Oh, and you're welcome!
