I have an input where the user writes a title, I need this title to have added (blog) to its end.

example: my title (blog) or your blog title

if it does not, I need to add this automatically or prevent sending the form with javascript or other language.

  • the software uses php, is a Wep app, the title will be saved in database.
php javascript html

    If you consider adding this automatically, you can relieve the user of this obligation and add it in PHP itself before recording it in the database. Something like: $titulo .= ' blog';

  • How would you do on the Laravel? i was considering using an html form, in which case I would have to take the exact value of the field in the validation to then add the tag (blog).

    I don’t know anything about Laravel :/

  • tranquil, php works too, I do a way here.

So we can make things easier by using javascript, for example, you can check if the value exists, if it exists, let it pass, otherwise, add, is a good one? To check using javascript we can use the string.indexOf("blog") != -1 if it does not contain "blog" in the string, it returns -1, if it does, it returns the position of the string.

If you are using an input, we can take the value and check each typed letter, we can trigger a function to each typed letter by adding the tag onkeyup for example, where we would check letter to letter.

Example for checking, remembering that use jquery to take the amount: 

<input type="text" id="texto" onkeyup="checar()">

<script type="text/javascript">
  function checar(){
    if($("#texto").val().indexOf("blog") != -1){return true;}
  }
</script>

We can check at the time of sending the form, and thus add in the string.

    good, it has problem be with jquery no, I am using bootstrap in form.

    Okay, it’ll be easy to do the check so you can even do this substitution on this function itself

    You don’t need else, because if you enter the if won’t even get into the return false.

    True friend, but the idea is he edit the function and adapt his reality. I will edit, in any case
