how do i validate the post form, for example, i want to make sure nobody can submit less then 300 words, no title less than 20 words etc?
And also it there a way that i can show the main category on a drop down menu and sun-category on another, instead of on the right side?
Thank You!

  • you can either validate using javascript(jquery) instantly on the webpage, or if your using a server side language i.e. php you would have to refresh the page and then show the error(very annoying)

    in terms of using jquery something like this would work for counting the characters including spaces:

    HTML:

    Code:
    <input type="text" id="post_body" name="post_body">
<input type="submit" id="check_before_posting" value="Submit">
    Javascript(JQUERY) :

    Code:
    // on submit click 
$("#check_before_posting").click(function() { 
   // get body value length
   body_value = $("#post_body").val.length;
   // if less than 300 alert error
    if(body_value < 300)
        alert("This is not allowed, body less than 300 characters");
});
  • thx very much. but where to put them?
  • and i am using wordpress
