Better Read More (in Link)

[AnAlienHolakres3]

Hello guys,
this is pretty simple thing - each link has its own "read more" link which refer to its own page. Sometimes it is not neccessary - if link description(content) is not long, user see nothing new and "read more" link is in this case useless. User can be confused also.

See the picture below. I also highlighted the link with a small arrow-image:

As you can see the first link has not read more,on the contrary the second link has it.

Requirements
This is really easy and simple modification which can be implemented to almost every version 0.9 version of Pligg. Personally I have yget template but there is a big chance this could be appliable to all templates.

Steps to do
- Make Backup of edited files

1) Open link.php in your libs folder
2) find $smarty->assign('link_submitter', $this->username()); and before that add following code:

PHP Code:

        // if link content < 160 chars then no "MORE" link
        if (strlen($this->content)>165){
        $smarty->assign('long_content',true);          
        }
        // end 


Save file.

3) Open link_summary.tpl in your /templates/template/ folder
find {if $pagename neq "story"} <a href="{$story_url}" style="text-decoration:none">
It is right after the section with extra fields.Change to wollowing:

{if $long_content eq true}{if $pagename neq "story"} <a href="{$story_url}" style="text-decoration:none"> .....{/if}{/if}

You can save. Thats all. Consider using picture just like me but it depends on you at all.

I have experienced a great issue when users CAN add some HTML tags to story content. The problem is that if html tags are used and story content is cutted to 165 characters, there will NOT be endtags.

What does it mean practically?
Big problem. Not only page is not valid, every story content will be then bold,italic or underlined also (depends on allowed tags).

Solution:
1) Disallow HTML tags in story.
2) Use my new hardcoded update.

It is funny that original idea was pretty simple but this is quite difficult because we need alternative story content with closed html tags.

Update:
Replace original code in link.php

PHP Code:

  // if link content < 160 chars then no "MORE" link
        if (strlen($this->content)>165){
        $smarty->assign('long_content',true);          
        }
        // end 


with

PHP Code:

         //*********************************************************************
        //READ MORE ADDON START
        
        // if link content < 160 chars then no "MORE" link
        if (strlen($this->content)>165){
        //find if text has unclosed tags
                              
        $cutted_content= utf8_substr($this->content,0,165);
        
        //shortest tag can be at least 3 chars long
        for ($i=0 ; $i<strlen($cutted_content)/3 ; $i++) {     
    
       //find html tag if previous tag position number was lower 
          if ($gtpos <= $i*3) {         
          $ltpos=stripos($cutted_content,"<",$i*3);
          $gtpos=stripos($cutted_content,">",$i*3);
          }else {
           
           $ltpos=stripos($cutted_content,"<",$ltpos+1);
           $gtpos=stripos($cutted_content,">",$gtpos+1);  
        
            } 
            //if tag was detected  
            if ($ltpos>-1 && $gtpos>-1){
          
          $tag=substr($cutted_content,$ltpos+1,$gtpos-$ltpos-1);
          // exclude empty tags and end tags    
          if(strlen($tag)>0 && substr($tag,0,1)!="/"){       
          $count[$tag]++;
          $tagname[]=$tag;
          }
          }else {
          //no more tags, no more cycles needed  
          break;   
          }  
          }
          
          
          //check if tag has its own closetag
        if ($tagname) {  
          
          $origtext=$cutted_content;  
       
          foreach ($tagname as $tagn) {
          
          $cltag=stripos($origtext,"</$tagn>");
          if ($cltag ==false){
            $addclosetags[]="</$tagn>";  
            }else {
            $origtext = substr($origtext,0,$cltag).substr($origtext,$cltag+strlen("</$tagn>"));   
            }            
         }
          if ($addclosetags){
            $addclosetags= array_reverse($addclosetags);
              $updated_content=$cutted_content;        
                  foreach ($addclosetags as $at){
                       $updated_content .=$at;
            }
        
         
        $smarty->assign('updated_content',$updated_content);
        $smarty->assign('add_closetags',true);
           } //update v 0.2
        }
        $smarty->assign('long_content',true);

Now open link_summary.tpl in your templates/yget/ folder and find

    {if $show_content neq 'FALSE'} ...something...{/if}

Replace it with:

{if $show_content neq 'FALSE'}
                    
                    {if $add_closetags eq true}
                    {if $pagename neq "story"} 
                    {$updated_content}
                    {else}
                    {$story_content}
                    {/if}
                    {else}
                    {$story_content}
                    {/if}

Now everything should work smoothly
