脚本宝典收集整理的这篇文章主要介绍了php – WordPress – 带分类列表的主题选项页面，脚本宝典觉得挺不错的，现在分享给大家，也给大家做个参考。
我现在的代码显示了类别名称列表,但也将名称回显到前端.我试图修改它的ID号,但我没有运气.
总而言之,在选项页面上,它需要在下拉列表中显示类别名称,但在前端它应该回显类别的ID号.
编辑：这是我用来创建选项页面的完整代码 – 这一切都在functions.PHP中：
<?PHP $themename = "TGH 2012"; $shortname = "tgh"; $categories = get_categories('hide_empty=0&orderby=name'); $wp_cats = array(); foreach ($categories as $category_list ) { $wp_cats[$category_list->cat_id] = $category_list->cat_name; } array_unshift($wp_cats,"Choose a category"); global $options; $options = array ( array( "name" => "Homepage Options","tyPE" => "tITle"),array( "type" => "open"),array( "name" => "Pick Categories","desc" => "Choose a category From the list to do some interesting stuff.","id" => $shortname."_categories","type" => "select","options" => $wp_cats,"std" => ""),array( "type" => "close") ); function mytheme_add_admin() { global $themename,$shortname,$options; if ( $_GET['page'] == basename(__FILE__) ) { if ( 'save' == $_REQUEST['action'] ) { foreach ($options as $value) { update_option( $value['id'],$_REQUEST[ $value['id'] ] ); } foreach ($options as $value) { if( isset( $_REQUEST[ $value['id'] ] ) ) { update_option( $value['id'],$_REQUEST[ $value['id'] ] ); } else { delete_option( $value['id'] ); } } header("Location: themes.PHP?page=functions.PHP&saved=true"); die; } else if( 'reset' == $_REQUEST['action'] ) { foreach ($options as $value) { delete_option( $value['id'] ); } header("Location: themes.PHP?page=functions.PHP&reset=true"); die; } } add_theme_page($themename." Options","".$themename." Options",'edit_themes',basename(__FILE__),'mytheme_admin'); } function mytheme_admin() { global $themename,$options; if ( $_REQUEST['saved'] ) echo '<div id="message" class="updated fade"><p><strong>'.$themename.' settings saved.</strong></p></div>'; if ( $_REQUEST['reset'] ) echo '<div id="message" class="updated fade"><p><strong>'.$themename.' settings reset.</strong></p></div>'; ?> <div class="wrap"> <h2><?PHP echo $themename; ?> settings</h2> <form method="post"> <?PHP foreach ($options as $value) { switch ( $value['type'] ) { case "open": ?> <table width="100%" border="0" style="background-color:#eef5fb; padding:10px;"> <?PHP break; case "close": ?> </table> <br /> <?PHP break; case "title": ?> <table width="100%" border="0" style="background-color:#dceefc; padding:5px 10px;"> <tr> <td colspan="2"><h3 style="font-family:Georgia,'Times New roman',Times,serif;"><?PHP echo $value['name']; ?></h3></td> </tr> <?PHP break; case 'text': ?> <tr> <td width="20%" rowspan="2" valign="middle"><strong><?PHP echo $value['name']; ?></strong></td> <td width="80%"><input style="width:400px;" name="<?PHP echo $value['id']; ?>" id="<?PHP echo $value['id']; ?>" type="<?PHP echo $value['type']; ?>" value="<?PHP if ( get_settings( $value['id'] ) != "") { echo get_settings( $value['id'] ); } else { echo $value['std']; } ?>" /></td> </tr> <tr> <td><small><?PHP echo $value['desc']; ?></small></td> </tr> <tr> <td colspan="2" style="margin-bottom:5px;border-bottom:1px dotted #000000;"> </td> </tr> <tr> <td colspan="2"> </td> </tr> <?PHP break; case 'textarea': ?> <tr> <td width="20%" rowspan="2" valign="middle"><strong><?PHP echo $value['name']; ?></strong></td> <td width="80%"><textarea name="<?PHP echo $value['id']; ?>" style="width:400px; height:200px;" type="<?PHP echo $value['type']; ?>" cols="" rows=""><?PHP if ( get_settings( $value['id'] ) != "") { echo get_settings( $value['id'] ); } else { echo $value['std']; } ?> </textarea></td> </tr> <tr> <td><small><?PHP echo $value['desc']; ?></small></td> </tr> <tr> <td colspan="2" style="margin-bottom:5px;border-bottom:1px dotted #000000;"> </td> </tr> <tr> <td colspan="2"> </td> </tr> <?PHP break; case 'select': ?> <tr> <td width="20%" rowspan="2" valign="middle"><strong><?PHP echo $value['name']; ?></strong></td> <td width="80%"><select style="width:240px;" name="<?PHP echo $value['id']; ?>" id="<?PHP echo $value['id']; ?>"> <?PHP foreach ($value['options'] as $option) { ?> <option<?PHP if ( get_settings( $value['id'] ) == $option) { echo ' selected="selected"'; } elseif ($option == $value['std']) { echo ' selected="selected"'; } ?>><?PHP echo $option; ?></option> <?PHP } ?> </select></td> </tr> <tr> <td><small><?PHP echo $value['desc']; ?></small></td> </tr> <tr> <td colspan="2" style="margin-bottom:5px;border-bottom:1px dotted #000000;"> </td> </tr> <tr> <td colspan="2"> </td> </tr> <?PHP break; case "checkBox": ?> <tr> <td width="20%" rowspan="2" valign="middle"><strong><?PHP echo $value['name']; ?></strong></td> <td width="80%"><? if(get_settings($value['id'])){ $checked = "checked=\"checked\""; }else{ $checked = ""; } ?> <input type="checkBox" name="<?PHP echo $value['id']; ?>" id="<?PHP echo $value['id']; ?>" value="true" <?PHP echo $checked; ?> /></td> </tr> <tr> <td><small><?PHP echo $value['desc']; ?></small></td> </tr> <tr> <td colspan="2" style="margin-bottom:5px;border-bottom:1px dotted #000000;"> </td> </tr> <tr> <td colspan="2"> </td> </tr> <?PHP break; } } ?> <!--</table>--> <p class="submit"> <input name="save" type="submit" value="Save changes" /> <input type="hidden" name="action" value="save" /> </p> </form> <form method="post"> <p class="submit"> <input name="reset" type="submit" value="Reset" /> <input type="hidden" name="action" value="reset" /> </p> </form> <?PHP } add_action('admin_menu','mytheme_add_admin'); ?> <?PHP if ( function_exists('register_sidebar') ) register_sidebar(array( 'before_widget' => '<li id="%1$s" class="widget %2$s">','after_widget' => '</li>','before_title' => '','after_title' => '',)); ?>
<?PHP global $options; foreach ($options as $value) { if (get_settings( $value['id'] ) === FALSE) { $$value['id'] = $value['std']; } else { $$value['id'] = get_settings( $value['id'] ); } } ?>
<?PHP echo $tgh_categories; ?>
foreach ($categories as $category_list ) {
$wp_cats[$category_list->cat_id] = $category_list->cat_name;
}
编辑
在这之后：
foreach ($categories as $category_list ) {
$wp_cats[$category_list->cat_ID] = $category_list->cat_name;
}
加：
$wp_ids = array();
foreach ($categories as $category_list ) {
$wp_ids[$category_list->cat_ID] = $category_list->cat_ID;
}
改变这个：
array( "name" => "Pick Categories",
对此：
array( "name" => "Pick Categories","cid" => wp_ids,
也改变这个：
case 'select':
?>
<tr>
<td width="20%" rowspan="2" valign="middle"><strong><?PHP echo $value['name']; ?></strong></td>
<td width="80%"><select style="width:240px;" name="<?PHP echo $value['id']; ?>" id="<?PHP echo $value['id']; ?>">
<?PHP foreach ($value['options'] as $option) { ?>
<option<?PHP if ( get_settings( $value['id'] ) == $option) { echo ' selected="selected"'; } elseif ($option == $value['std']) { echo ' selected="selected"'; } ?>><?PHP echo $option; ?></option>
<?PHP } ?>
</select></td>
</tr>
<tr>
<td><small><?PHP echo $value['desc']; ?></small></td>
</tr>
<tr>
<td colspan="2" style="margin-bottom:5px;border-bottom:1px dotted #000000;"> </td>
</tr>
<tr>
<td colspan="2"> </td>
</tr>
<?PHP
break;
对此：
case 'select':
?>
<tr>
<td width="20%" rowspan="2" valign="middle"><strong><?PHP echo $value['name']; ?></strong></td>
<td width="80%"><select style="width:240px;" name="<?PHP echo $value['id']; ?>" id="<?PHP echo $value['id']; ?>">
<?PHP foreach ($value['options'] as $option) { ?>
<option value="<?PHP echo $value['cid']; ?>" <?PHP if ( get_settings( $value['id'] ) == $option) { echo ' selected="selected"'; } elseif ($option == $value['std']) { echo ' selected="selected"'; } ?>><?PHP echo $option; ?></option>
<?PHP } ?>
</select></td>
</tr>
<tr>
<td><small><?PHP echo $value['desc']; ?></small></td>
</tr>
<tr>
<td colspan="2" style="margin-bottom:5px;border-bottom:1px dotted #000000;"> </td>
</tr>
<tr>
<td colspan="2"> </td>
</tr>
<?PHP
break;
编辑
我的坏,我忘记了$
改变这个：
"cid" => wp_ids,
至：
"cid" => $wp_ids,
新编辑
改变这个：
<tr> <td width="20%" rowspan="2" valign="middle"><strong><?PHP echo $value['name']; ?></strong></td> <td width="80%"><select style="width:240px;" name="<?PHP echo $value['id']; ?>" id="<?PHP echo $value['id']; ?>"> <?PHP foreach ($value['options'] as $option) { ?> <option value="<?PHP echo $value['cid']; ?>" <?PHP if ( get_settings( $value['id'] ) == $option) { echo ' selected="selected"'; } elseif ($option == $value['std']) { echo ' selected="selected"'; } ?>><?PHP echo $option; ?></option> <?PHP } ?> </select></td> </tr>
对此：
<tr> <td width="20%" rowspan="2" valign="middle"><strong><?PHP echo $value['name']; ?></strong></td> <td width="80%"><select style="width:240px;" name="<?PHP echo $value['id']; ?>" id="<?PHP echo $value['id']; ?>"> <?PHP $categories = get_categories('hide_empty=0&orderby=name'); foreach ($categories as $category_list ) { ?> <option value="<?PHP echo $category_list->cat_ID; ?>" <?PHP if ( get_settings( $value['id'] ) == $category_list->cat_name) { echo ' selected="selected"'; } elseif ($category_list->cat_name == $value['std']) { echo ' selected="selected"'; } ?>><?PHP echo $category_list->cat_name; ?></option> <?PHP } ?> </select></td> </tr>
