  • 0

I have been trying everything to try and solve this myself, but cannot find any solutions on google or my beginner php skills are not up to the task. So please can someone show me how I can make the form submit ONLY if people have written 15 words or more. Any suggestions would be very much appreciated. Below is the css, javascript and html.

#container { 
    background: #ededed; 
    border: 1px solid #ddd; 
    margin: 0 auto; 
    padding: 10px;
    position: relative;
    width: 638px;
}

.error { color: #f00; }

ol.forms { list-style: none; overflow: hidden; }
ol.forms li { float: left; margin-bottom: 12px; width: 100%; }
ol.forms label { cursor: pointer; display: block; }
ol.forms textarea {
    border: 1px solid #ddd;
    float: left; 
    font: 14px/1.5em Georgia, Times, serif; 
    height: 120px; 
    margin-right: 5px;
    overflow-y: auto; 
    padding: 5px;
    width: 500px; 
}
ol.forms textarea:focus { border: 1px solid #000; }
ol.forms div.wordCount { float: left; font-size: 20px; line-height: 30px; }

#quick50 {
    background: #fff;
    border: 1px solid #ddd;
    font-size: 11px;
    left: 5px; 
    padding: 5px;
    position: fixed; 
    width: 188px; 
}

$(document).ready(function() {
    $("[class^='count[']").each(function() {
        var elClass = $(this).attr('class');
        var description = 0;
        var maxWords = 0;
        var countControl = elClass.substring((elClass.indexOf('['))+1, elClass.lastIndexOf(']')).split(',');

        if(countControl.length > 1) {
            description = countControl[0];
            maxWords = countControl[1];
        } else {
            maxWords = countControl[0];
        }

        $(this).after('<div class="wordCount"><strong>0</strong> Words</div>');
        if(description > 0) {
            $(this).siblings('.wordCount').addClass('error');
        }

        $(this).bind('keyup click blur focus change paste', function() {
            var text = jQuery.trim($(this).val()).replace(/\s+/g," ");
            var numWords = text.split(' ').length;
            if($(this).val() === '') {
                numWords = 0;
            }   
            $(this).siblings('.wordCount').children('strong').text(numWords);

            if(numWords < description || (numWords > maxWords && maxWords != 0)) {
                $(this).siblings('.wordCount').addClass('error');
            } else {
                $(this).siblings('.wordCount').removeClass('error');    
            }

        });

    });
});

    Off the top of my head, something like this?

    <textarea id="some-textarea" onkeypress="activateSubmit();">
</textarea>
<input type="submit" value="Submit" id="submit-button" disabled="disabled">

    And correspondingly somewhere:

    <script>
  function activateSubmit(){
    var len = $('#some-textarea').val().split(" ").length;
    if(len >= 15){ //15 words, hardcoded, probably change this to maxwords, or whatever.
      $('#submit-button').removeAttr('disabled');
    }
    else{
      $('#submit-button').attr('disabled', 'disabled');
    }
  }
</script>
