Configurable Tag Cloud Update:
A lot of popular WordPress plugins have not been properly updated for several years now, and contain deprecated code. While the plugin may seem "fine" when its activated in wp-admin, deprecated code often means that it's not functioning properly. This tends to only be noticed when you enable debug mode in the
wp-config.php file.
Configurable Tag Cloud gives the following error when activated:
Code:
Notice: has_cap was called with an argument that is deprecated since version 2.0! Usage of user levels by plugins and themes is deprecated. Use roles and capabilities instead. in X:\...\wp-includes\functions.php on line 2722
Notice: has_cap was called with an argument that is deprecated since version 2.0! Usage of user levels by plugins and themes is deprecated. Use roles and capabilities instead. in X:\...\wp-includes\functions.php on line 2722
These refers to permissions based on user levels (old, wrong) vs permissions based on capabilities (new, correct).

Between lines 59 and 94 of
admin_page.php are 8 lines of code that begin with "input style" and contain deprecated code
wp_specialchars()
Code:
<td><input style="text-align:right" type="text" id="ctc-number" name="ctc-number" value="<?php echo wp_specialchars($options['number'], true); ?>" /></td>
<td><input style="text-align:right" type="text" id="ctc-minnum" name="ctc-minnum" value="<?php echo wp_specialchars($options['minnum'], true); ?>" /></td>
<td><input style="text-align:right" type="text" id="ctc-maxnum" name="ctc-maxnum" value="<?php echo wp_specialchars($options['maxnum'], true); ?>" /></td>
<td><input style="text-align:right" type="text" id="ctc-smallest" name="ctc-smallest" value="<?php echo wp_specialchars($options['smallest'], true); ?>" /></td>
<td><input style="text-align:right" type="text" id="ctc-largest" name="ctc-largest" value="<?php echo wp_specialchars($options['largest'], true); ?>" /></td>
<td><input style="text-align:right" type="text" id="ctc-mincolor" name="ctc-mincolor" value="<?php echo wp_specialchars($options['mincolor'], true); ?>" /></td>
<td><input style="text-align:right" type="text" id="ctc-maxcolor" name="ctc-maxcolor" value="<?php echo wp_specialchars($options['maxcolor'], true); ?>" /></td>
These need to be changed to
esc_html() instead:
Code:
<td><input style="text-align:right" type="text" id="ctc-number" name="ctc-number" value="<?php echo esc_html($options['number'], true); ?>" /></td>
<td><input style="text-align:right" type="text" id="ctc-minnum" name="ctc-minnum" value="<?php echo esc_html($options['minnum'], true); ?>" /></td>
<td><input style="text-align:right" type="text" id="ctc-maxnum" name="ctc-maxnum" value="<?php echo esc_html($options['maxnum'], true); ?>" /></td>
<td><input style="text-align:right" type="text" id="ctc-smallest" name="ctc-smallest" value="<?php echo esc_html($options['smallest'], true); ?>" /></td>
<td><input style="text-align:right" type="text" id="ctc-largest" name="ctc-largest" value="<?php echo esc_html($options['largest'], true); ?>" /></td>
<td><input style="text-align:right" type="text" id="ctc-mincolor" name="ctc-mincolor" value="<?php echo esc_html($options['mincolor'], true); ?>" /></td>
<td><input style="text-align:right" type="text" id="ctc-maxcolor" name="ctc-maxcolor" value="<?php echo esc_html($options['maxcolor'], true); ?>" /></td>
Also in
admin_page.php at line 151 is a deprecated reference to user level 8:
Code:
add_options_page('CTC', 'CTC', 8, 'ctcoptions', 'ctc_options_page');
Change to
activate_plugins():
Code:
add_options_page('CTC', 'CTC', 'activate_plugins', 'ctcoptions', 'ctc_options_page');
Between line 272 and 281 of
base.php are 4 lines of deprecated code
attribute_escape(),
wp_specialchars() and
clean_url()
Code:
$tag_link = clean_url($tag_links[$tag]);
$tag = wp_specialchars($tag);
$a[] = "<li class=\"ctc-tag-li\"><a href=\"$tag_link\" class=\"ctc-tag tag-link-$tag_id\" title=\"".attribute_escape(sprintf(__('%d topics'), $count))."\"$rel style=\"font-size: ".$tag_weight
$a[] = "<a href=\"$tag_link\" class=\"ctc-tag tag-link-$tag_id\" title=\"".attribute_escape(sprintf(__('%d topics'), $count))."\"$rel style=\"font-size: ".$tag_weight
These need to be replaced with
esc_attr(),
esc_html, and
esc_url (respectively):
Code:
$tag_link = esc_url($tag_links[$tag]);
$tag = esc_html($tag);
$a[] = "<li class=\"ctc-tag-li\"><a href=\"$tag_link\" class=\"ctc-tag tag-link-$tag_id\" title=\"".esc_attr(sprintf(__('%d topics'), $count))."\"$rel style=\"font-size: ".$tag_weight
$a[] = "<a href=\"$tag_link\" class=\"ctc-tag tag-link-$tag_id\" title=\"".esc_attr(sprintf(__('%d topics'), $count))."\"$rel style=\"font-size: ".$tag_weight
Between lines 61 and 100 of
widget.php are 8 lines of code with deprecated code
wp_specialchars()
Code:
<td><input style="text-align:right" type="text" id="title" name="title" value="<?php echo wp_specialchars($options['title'], true); ?>" /></td>
<td><input style="text-align:right" type="text" id="number" name="number" value="<?php echo wp_specialchars($options['number'], true); ?>" /></td>
<td><input style="text-align:right" type="text" id="minnum" name="minnum" value="<?php echo wp_specialchars($options['minnum'], true); ?>" /></td>
<td><input style="text-align:right" type="text" id="maxnum" name="maxnum" value="<?php echo wp_specialchars($options['maxnum'], true); ?>" /></td>
<td><input style="text-align:right" type="text" id="smallest" name="smallest" value="<?php echo wp_specialchars($options['smallest'], true); ?>" /></td>

<td><input style="text-align:right" type="text" id="mincolor" name="mincolor" value="<?php echo wp_specialchars($options['mincolor'], true); ?>" /></td>
<td><input style="text-align:right" type="text" id="maxcolor" name="maxcolor" value="<?php echo wp_specialchars($options['maxcolor'], true); ?>" /></td>
These need to be changed to
esc_html() instead:
Code:
<td><input style="text-align:right" type="text" id="title" name="title" value="<?php echo esc_html($options['title'], true); ?>" /></td>
<td><input style="text-align:right" type="text" id="number" name="number" value="<?php echo esc_html($options['number'], true); ?>" /></td>
<td><input style="text-align:right" type="text" id="minnum" name="minnum" value="<?php echo esc_html($options['minnum'], true); ?>" /></td>
<td><input style="text-align:right" type="text" id="maxnum" name="maxnum" value="<?php echo esc_html($options['maxnum'], true); ?>" /></td>
<td><input style="text-align:right" type="text" id="smallest" name="smallest" value="<?php echo esc_html($options['smallest'], true); ?>" /></td>
<td><input style="text-align:right" type="text" id="largest" name="largest" value="<?php echo esc_html($options['largest'], true); ?>" /></td>
<td><input style="text-align:right" type="text" id="mincolor" name="mincolor" value="<?php echo esc_html($options['mincolor'], true); ?>" /></td>
<td><input style="text-align:right" type="text" id="maxcolor" name="maxcolor" value="<?php echo esc_html($options['maxcolor'], true); ?>" /></td>
And that's it.
