Set the minimum number of characters for the tags.

[clems365]

Hi all

Like the title story or story description, I would like to make the same for the tags clouds (min characters 4).

I saw in the database and make a look :

 (71, 'Submit', 'minTitleLength', '10', '10', 'number', 'Minimum Title Length', 'Set the minimum number of characters for the story title.', 'define', NULL), 
  

It could be something like that:

 (71, 'tags', 'minTagLength', '4', '4', 'number', 'Minimum Tags Length', 'Set the minimum number of characters for the tags.', 'define', NULL), 
  

I believe it will be more or less the same, but... I don't now how to make it

Somebody could help me

Thanks a lot

Best regards

Clément

There is no feature to set the number of characters for the tag word in the admin pannel. You might try this while users submit a story.

Open /yourtemplate/submit_step_2.tpl and insert the following code within the {literal} {/literal}

<SCRIPT language="JavaScript">
<!--
function checkTags() {
 var tags=window.document.thisform.tags.value
  if (tags=="") {
   alert('Please enter at least one tag');
   window.document.thisform.tags.focus();
   exit;
  }
  if (tags.indexOf(",")== -1) {
   if (trim(tags).length < 4) {
    alert("The tag word must be at least 4 characters. Please correct it.");
   }
  }
  if (tags.indexOf(",")!= -1) {
   var tag_array=window.document.thisform.tags.value.split(",");
   var tags_num=0;
   while (tags_num < tag_array.length) {
    if (trim(tag_array[tags_num]).length < 4) {
       alert("The tag '" + tag_array[tags_num] + "' is less than 4 characters. Please correct it.");
      }
      tags_num+=1;
     }
  }
}
 
function trim(str) {
   return str.replace(/^\s+|\s+$/g,'');
}
//-->
</SCRIPT>

Go to this line where the input fields for the tags is and add the red part:

<input type="text" id="tags" name="tags" value="{$tags_words}" size="60" maxlength="40" onClick="checkTags();"/>

Now, as soon as the Tags field looses focus. the function checks the following:

1. If the Tags field is empty, it alerts the user, gives the focus back to this field and exit the function.
2. If only one tag was entered (no comas), it trims the value and checks its length. If the length is less than 4, it sends an alert.
3. If more than one tag were entered, it splits and iterates through the tags and checks the trimmed length for each. If the length is less than 4, it sends an alert.

I hope this helps
