Good night, you guys.

One more trick I’m in doubt in my system. I’ve done everything at the beginning of the page with PHP to do a search in my database. But there is a field that I am bringing through the mysqli_fetch_array that I need to bring in the original formatting that was typed in a textarea of a form.

Ai at the time of bringing I created this line in my HTML (But it went wrong):

<input type="text" id="texto-os" style="height: 150px;" name="texto_os" class="form-control" placeholder="Descreva o Serviço" value="<?php echo '<pre>'.$dados_os['ordem_servico'].'</pre>'?>

The result of this is: (All in one row (even though it was recorded with line breaks, and showing the tag as if it had not been running them.

<pre>Texto que vem do Banco de Dados</pre>

I even switched to <input type="text>"because when I was in <textarea> did not show my Database content.

Anyway, in other codes I use the tag after echo to bring the original formatting, but this usually I did at once in the file only with PHP.

This time for practicality, I’m bringing field to field the answers to fill out my form since I still don’t know how to do it via Javascript.

I’m doing wrong or really have no way to use pre inside the html tag value?

  • You really need to put the <pre></pre> within the <textarea> ? I tested it here and it didn’t work, I don’t think I can.

  • So, is that this field will be a Service Order Summary. So one will type a lot in a few broken lines. Sure. Then to be better to visualize, I will need to treat this text in some way.

The <input type="text"> accepts only one line, and there is no way to add HTML within value:

<input type="text" value="<pre>olá

Mundo</pre>">

And <br> it won’t work either:

<input type="text" value="olá<br>Mundo">

That’s not how HTML works.

What you should do is change input=text for textarea, thus:

<textarea rows="10" cols="30">olá

Mundo</textarea>

  • That is, in case I returned to use the textarea and put my php command between opening and closing the tag, ai using nl2br and strip_tags was perfect.

  • @Rafael has no sense to use nl2br and then use strip_tags, that is extremely redundant. It would be better to just use direct strip_tags, in case you have HTML content in the mysql result, if you don’t even have strip_tags makes sense, I need to be honest but I think you are confusing what is happening.

    True, I had tried without it, but had left a typo that gave me error. I did not know that only in returning the text would come already with the initial formatting. Thanks for the tip, helped my dear.

To bring the result of the bank with line break use the function nl2br.

In your case it looks like this:

<input type="text" id="texto-os" style="height: 150px;" name="texto_os" class="form-control" placeholder="Descreva o Serviço" value="<?php echo strip_tags(nl2br($dados_os['ordem_servico']))?>

  • Oh indeed, I didn’t remember nl2br, but it brings my code showing <br /> where should I break the line. Will I have to treat this with javascript? It looks like this. Computador com virus.<br />Não abre Navegador.

  • I edited the answer, now I set the function strip_tags also, see if it works.

  • Oh cool, that works. But not within the value. What I did then was take <input type="text"> and use the <textarea>. Staying now like this: <textarea id="texto-os" style="height: 150px;" name="texto_os" class="form-control" placeholder="Descreva o Serviço"><?php echo strip_tags(nl2br($dados_os['ordem_servico']))?></textarea>. It gave right now. Thanks really Leandro, helped a lot
