pattern match

[glenelkins]

hi

 

say i have this string:

 

{cms type="textarea" name="qdos_entertainment_plc_para_1" cols="75" rows="5" style="border: 1px solid #000000;padding: 5px;"}

 

I want to match this:

 

{cms HERE CAN HAVE ANYTHING IN ANY ORDER BUT MUST HAVE name="NAME_HERE"} ANYTHING HERE {/cms}

 

what would be the expression?

[aschk]

Something like this:

 

"/{cms(.+)[^(name=\"(.*)\")](.+)}/"

 

Probably won't work but might give a basis for whatever you're after.

[glenelkins]

basically i need it to match {cms name="bla bla"}(.*){/cms}

 

the part with the name bit is essential but there could be more params before or after it which should just be ignored

 

so for example, this is not valid

 

{cms type="textarea" rows="10" cols="5"}CONTENT TO RETURN HERE{/cms}

 

But this is valid

 

{cms name="blb lfdnjk" type="textarea" rows="10" cols="5"}CONTENT TO RETURN HERE{/cms}

 

And this is valid

 

{cms type="textarea" rows="10" cols="5" name="bla bla"}CONTENT TO RETURN HERE{/cms}

 

and this is also valid

 

{cms name="bla bla"}CONTWENT{/cms}

Give this a try...

 

preg_match('/\{cms[^\}]*name="[^"]+"[^\}]*\}[^\{]+\{\/cms\}/', $str);

[glenelkins]

MrAdam that is almost there i think. Check my longer post above, basically it needs to find the tag with the name="whatever" and return whats between the {cms}...{/cms} bit

 

so say i have {cms name="test" type="bla bla"}CONTENT HERE{/cms}

 

I have a var like $name = 'test'

 

it needs to go through the content i have looking for the cms tag with the name="$name" and return whats between the beginning and end tags, but the name parameter is allowed to fall anywhere within the first tag before or after any other param

[Adam]

The regular expressions is right, it's just modifying the function a little bit now to return the matches.

 

preg_match_all('/\{cms[^\}]*name="[^"]+"[^\}]*\}[^\{]+\{\/cms\}/', $str, $matches);

print_r($matches);

 

The $matches array will contain what you're after...

[glenelkins]

but it doesnt!

 

if i have the tag as this:

 

{cms type="textarea" name="qdos_entertainment_plc_para_1" cols="75" rows="5" style="border: 1px solid #000000;padding: 5px;"}Chaired by Nick Thomas, the company he created in 1986 is now one of the largest, broad-based entertainment Groups in the UK. Focussed on family entertainment and traditional values, the Group has grown both organically and through a steady 'buy & build' strategy focusing on businesses that complement the original model, managed by a coherent holding company.{/cms}

 

the array only comes back with position 0 there are no other elements so all its doing is returning the entire string i pasted above. what i want to do is get the actual content between the tags and replace it with something else

[aschk]

Put a bracket in the right place then

 

preg_match_all('/\{cms[^\}]*name="([^"]+)"[^\}]*\}[^\{]+\{\/cms\}/', $str, $matches);

[Adam]

Oh sorry I see. Try this:

 

preg_match_all('/\{cms[^\}]*name="[^"]+"[^\}]*\}([^\{]+)\{\/cms\}/', $str, $matches);

print_r($matches);

 

Let me know if this is what you're after...

[glenelkins]

ah i got it i think!

 

/\{cms[^\}]*name="[^"]+"[^\}]*\}(.*){\/cms\}/

[glenelkins]

ok here is 1 more issue with this

 

the expression /\{cms[^\}]*name="[^"]+"[^\}]*\}(.*){\/cms\}/  seems to work, but if the content has a special charcter say an apostraphie, it seems to stop matching at the symbol and cuts the text off

 

so in this example text below it cuts off right after "'buy"

[Adam]

The last example I sent you works.

[glenelkins]

it doesnt! it cuts the text off like this:

unless thats the javascript doing that when i send the string to the ajax file

[glenelkins]

it was the js doing it. i just added the escape function

 

thanks for your help

[Adam]

You need to escape your single quotes. How exactly are you returning the string which contains the cms tags?

 

EDIT: Excellent!

[glenelkins]

another quick question... now i have the content from the middle and i have it replacing with preg_replace  how can i actually return everything thats between {cms params here} because i dont actually want to replace the {cms PARAMS}...{/cms} bits just whats between them
