It is not currently working for me. I edited the error message to output the $selectRequiredCount value. It doesn't appear that this variable is being incremented.</p> <p>Where does the new function validate_blank get called? </p> https://www.machform.com/forums/topic/limit-number-of-fields-by-user#post-2350 Tue, 15 Jul 2008 11:16:56 +0000 redityo 2350@https://www.machform.com/forums/ <p>Hi ..</p> <p>From your case you only want user to fill 10 from 50 Drop down right? you can try this modification to your machform :</p> <p>1. modify includes/post-functions.php</p> <p>#bellow line 131 </p> <pre><code>//count variable $selectRequiredCount = 0;</code></pre> <p>#between line 630 ~ 632, replace</p> <pre><code>if($validation_result !== true){ $error_elements[$element_id] = $validation_result; }</code></pre> <p>to</p> <pre><code>//add rule blank check $rules[$element_name][&#39;blank&#39;] = true; if($validation_result !== true){ if ($validation_result !== &quot;BLANK&quot;) $error_elements[$element_id] = $validation_result; else $selectRequiredCount++; }</code></pre> <p>#in line 948, add</p> <pre><code>if ($selectRequiredCount &lt;&gt; 40) { $process_result[&#39;status&#39;] = false; $process_result[&#39;custom_error&#39;] = &quot;you must fill 10 entries&quot;; return $process_result; }</code></pre> <p>2. modify include/common-validator.php</p> <p>#in line 39</p> <pre><code>//validation for blank function validate_blank($value){ $value = $value[0]; if(empty($value)) { //0 and &#39;0&#39; should not considered as empty return &#39;BLANK&#39;; }else{ return true; } }</code></pre> https://www.machform.com/forums/topic/limit-number-of-fields-by-user#post-2349 Tue, 15 Jul 2008 08:45:49 +0000 walags 2349@https://www.machform.com/forums/ <p>This is what I would like to accomplish...say you have 50 drop down fields and you only want a user selecting a response for 10 of them, where do I start?</p> <p>I am assuming there is an easy function to see if a field is empty or not. Similar to the checking in place for required fields, I want to count how many fields are empty and prevent the user from submitting if it is more or less then I say so. In the example above I would want to have a total of 40 empty fields...no more no less.</p> <p>Could you see a function like this work in this environment? </p>
