[MOD] Adding {ifno tagname1}{tagname2}{endifno tagname1} v1.7/v1.7.1

[V@no]

This little extra feature will let u use those kind of tags in templates:
{ifno tagname1}
 {tagname2}
 or page content
{endifno tagname1}
What does it mean?
It will display whatever is registered in {tagname2} if {tagname1} is empty or set as 0
the format is the same as {if tagname}{tagname} or whatever else{endif tagname} but works opposite

For 4images v1.7

Find:

Code: [Select]

 function replace_if($template) {
    foreach ($this->key_cache as $key => $val) {

        $reg = "/".$this->start."if[ \t\r\n]+".$key.$this->end."(.*)".$this->start."endif[ \t\r\n]+".$key.$this->end."/siU";

Tried it and got:

Fatal error: Call to undefined function: replace_ifno() in /*****/*****/*****/includes/template.php on line 128

Also do I just put the content if no thumbnails in {tag2} in categories.html say:

{ifno tag1}
Content here
{endifno tag1}

Line 128 is:
    $template = $this->replace_ifno ($template);

Thanks

ops, sry about that...I first make it as {ifnot...} then after posting, edited...
delete t in this line:
function replace_ifnot($template) {

P.S. I corrected the post.

[widgit1981]

Thanks I just noticed it before you posted.

Might be worth to mention to make it work you need to change tag1 into something say:

{ifno thumbnails}
Content here
{endifno thumbnails}

To say if no thumbnails are in the category show "content here" I know I got a little confused.

Thanks

Steve

[V@no]

it works exactly the same as {if tagname}
just replace tag1 with name of your tag.

[widgit1981]

Thanks

I just discovered it myself and was editing my post while you where writing your post lol

Thanks again you wouldn't believe how much this has helped. Will this thread become sticky cuz I think a few people would like to know this.

Steve

[V@no]

I didnt want make it sticky, because it's actualy for little more "advanced" ppl (not everyone out there even knows what {...} means )
but if u guys think it worth to be sticky, then be it

[widgit1981]

Ohhh I am in the advanced class ??? LOL

We'll see if anyone replies to the post and see if they want it to be.

Thanks again.

Steve
