    I have a form which processes and stores the information in my database. I then call the information back and store it as a variable to display in the value of the input, so it can be edited and updated. For testing I am also echoing the the variable directly after text area for comparison.

    Description: <textarea name="description" rows="5" cols="40"><?php echo $description;?></textarea>

<?php echo $description;?>

    When the echos print the one in the testarea has a </br> which isn’t present in the other echo.

    The textarea text prints as follows

    Test paragraph one.
    Test paragraph two.

    Where as the regular echo prints as follows.

    Test paragraph one.
    Test paragraph two.

    This is a problem because if someone say updates their email address and doesn’t change the description and clicks save. It gets saved with the <br /> in there.

    What do I need to do to prevent the <br /> from being added?

    Format correction:

    The textarea text prints as follows

    Test paragraph one.<br />
    Test paragraph two.

    How are you saving the data to the database? Is the
    in your database after you save the description the first time, or only the second time?

    It only shows up when I echo it in an input. It isn’t in the database unless I save again once it has been added in the input.

    FYI, the break is in the echo in both cases. When echoed normally, any HTML is interpreted, but when echoed inside of textareas, any HTML is not interpreted. View your page’s source HTML to see for yourself.

    Which doesn’t really matter because you do not want it whether it’s displayed or not. I’ve no idea where it’s being inserted, other than between retrieval and echo. What code is used for this? Even if the actual code is not inserting anything, there could be a filter being applied that adds in the breaks.

    As a workaround, you could use wp_strip_all_tags() prior to echoing out the textarea content. Of course this would also strip links and formatting HTML as well, which could be a good thing, or not. If you need other HTML to be maintained, you could strip out only breaks with preg_replace().

    Depending on what the textarea content is ultimately used for, the inserted break could be beneficial. Echoing the textarea content as normal markup would require the breaks to be inserted. Otherwise, the original newline characters are ignored and the separate lines without breaks would run together. Consider this when deciding to remove the altering code or work around it.
