I made a text box to input number and after the user click the save button, it will save the value into the wp_postmeta.

But, the problem is that, after I refresh the page the number will content with space character.

Like this:

enter image description here


<div class = "meta-td03">
                <input type="text" class="dwwp-row-content03" name="bonus_point" id="bonus_point" value="
                        if ( ! empty ( $dwwp_stored_meta['bonus_point'] ) ) {
                            echo esc_attr($dwwp_stored_meta['bonus_point'][0] );

Save function:

if ( isset( $_POST[ 'bonus_point' ] ) ) {
        update_post_meta( $post_id, 'bonus_point', sanitize_text_field( $_POST[ 'bonus_point' ] ) );

And I go to the database, and the value actually is 86.

This problem is came after I changed the editor to Eclipse from netBean. And I tried to go back netBean, but it isn't work. How to fix this problem? Thx a lot.

    The problem is new lines inside value attribute. Have you tried: value="<?php if (...) ?>". – MinhTri Aug 25 '16 at 4:21
  • Oh YS thx! Problem is fixed. But why this problem appear? – Capslock10 Aug 25 '16 at 4:34
  • @Capslock10 the problem is that you hit the enter key after your value=" then you opened your <?php tag, so before the <?php tag and after your = you have a new line! – bynicolas Aug 25 '16 at 4:38

Like @Dan9 said, you have a new line inside your value attribute.

you can write your conditional statement this way too

<div class = "meta-td03">
  <input type="text" class="dwwp-row-content03" name="bonus_point" id="bonus_point" value="<?php ! empty( $dwwp_stored_meta['bonus_point'] ) ? echo esc_attr($dwwp_stored_meta['bonus_point'][0] ) : ''; ?>" />
  • Thx a lot. Is it the attribute should inside one line? As it make the line so long... – Capslock10 Aug 25 '16 at 4:39
  • You can break line inside the <?php ?> tag but any new line outside of PHP tags will be considered HTML so it will be rendered by the browser. I don't make new lines when it's not necessary, especially to avoid this kind of issues! – bynicolas Aug 25 '16 at 4:43
