Question

I m trying to submit a form without a submit button. This form takes values from custom fields in wordpress, displaying results in another page. I ve been trying with the usual javascript function onchange and nothing happens, I ve tried with functions as well...does anyone know what s wrong with this or if is there a better way to solve it? Can it be something related to Wordpress, or the post method? This is the code for the form:

<form method="get" name="form" action="/busqueda/" >
        <div class="search">

            <select class="styled" name="author"  onChange="this.form.submit();">
            <option value="-1" selected>Authors</option>    
            <?php
            $metakey =  author ;
            $autores = $wpdb->get_col($wpdb->prepare("SELECT DISTINCT meta_value FROM $wpdb->postmeta WHERE meta_key = %s ORDER BY meta_value ASC", $metakey) );
            if ($authors) {
            foreach ($authors as $author) {
            echo "<option VALUE="" . $author . "">" . $author . "</option>";
                                    }
                            }
                ?>
            </select>
        </div><!-- #search1 -->

</form>

BTW, the form works fine when displaying results with a standard submit button. Any hint of what can be wrong is welcome. Thanks a lot!

引证:

<form method="get" name="form" action="/busqueda/" >
        <div class="search">

            <select class="styled" name="author" onChange="document.forms[ form ].submit();">

            <?php
            $metakey =  author ;
            $autores = $wpdb->get_col($wpdb->prepare("SELECT DISTINCT meta_value FROM $wpdb->postmeta WHERE meta_key = %s ORDER BY meta_value ASC", $metakey) );
            if ($authors) {
            foreach ($authors as $author) {
            echo "<option VALUE="" . $author . "">" . $author . "</option>";
                                    }
                            }
                ?>
            </select>
        </div><!-- #search1 -->

</form>

Updated with jQuery submit

最新表格:

<form id="authorForm" method="get" name="form" action="/busqueda/" >
        <div class="search">

            <select id="author" class="styled" name="author">
                <option value="default">Choose an author...</option>
                <?php
                $metakey =  author ;
                $autores = $wpdb->get_col($wpdb->prepare("SELECT DISTINCT meta_value FROM $wpdb->postmeta WHERE meta_key = %s ORDER BY meta_value ASC", $metakey) );
                if ($authors){
                    foreach ($authors as $author) {
                        echo  <option value="  . $author .  ">  . $author .  </option> ;
                    }
                }
                ?>
            </select>
        </div><!-- #search1 -->

</form>

j 文字改变活动处理和形式提交:

<script type="text/javascript">
$(document).ready(function(){
    $( #author ).change(function(){
        if($(this).val() !==  default ){
            $( #authorForm ).submit();
        }
    }); 
});
</script>

我希望你将员额后的价值正确地从GET美元中收回,因为如果在我的浏览器上操作该代码,URL的数值就会相当高。检查你的检索代码,确保你使用_GET,而不是_POST。
