PHP-在div中从mysql文本字段显示html

Question

I've some problem with displaying html tags after I retrieve them from a text field in my mysql DB.

my code looks something like this:

<div class='textDiv'><? echo htmlspecialchars_decode(str_replace("\r\n", "<br>", $row["textField"]), ENT_NOQUOTES);?></div>

So when the text field in mysql has only plain text, everything is fine, but when I add a link inside the text, I get a line break before and after the link tag, and the displayed text becomes line this:

Some text justified over the div, then a sudden break
text with link to source
then the text continues justified as normal

However, HTML code generated by the script is like this:

<div class="textDiv">Senior Advisor said in a <a href="test.html">media interview</a> that the overall monetary policy tone is shifting towards...</div>

Do you guys have any idea why this happens and how to fix it? So that the text is displayed smoothly without line breaks?

Answer 1

When you are using htmlspecialchars_decode all of the text's html is being decoded , so if you want to keep the decode function

1)Change the link in to how a normal link will look like , eg : yourwebsite.com/test.html don't add the tag

2) Don't echo string directly do this

$text = htmlspecialchars_decode(str_replace("\r\n", "<br>", $row["textField"]);

3) Then pass the variable $text to code to detect links , here is one :-

        $reg_exUrl = '@((https?://)?([-\w]+\.[-\w\.]+)+\w(:\d+)?(/([-\w/_\.\,]*(\?\S+)?)?)*)@';
    if(preg_match($reg_exUrl, $text, $url)) {
    echo preg_replace($reg_exUrl, '<a href="https://'.$url[0].'" rel="nofollow">'.$url[0].'</a>', $text);
    } 
    else 
    {
    echo $text;
    }

You can change the code to adjust to your needs
