[英]in an update, how to select an option from a select box?
下午好,
使用cakephp,如何在更新操作中的选择框中选择值?
在视图中,我得到这样的变量,例如:
<?php $category = $itemEditar['Anuncio']['category']; ?>
我需要从选择框中选择一个选项:
<select id="select_category" name="enquiry">
<option value="" >selecione</option>
<option value="Category1">Categoria1</option>
<option value="Category2">Categoria2</option>
<option value="Category3">Categoria2</option>
</select>
要进行更新操作,我需要标记数据库中保存的类别,并且我没有得到如何执行此操作。
您想要针对每个选项或选项检查$ category,如果匹配则设置所选属性。
<select id="select_category" name="enquiry">
<option value="" >selecione</option>
<option<?= $category == "Category1"?" selected = 'selected'":"" ?> value="Category1">Categoria1</option>
<option<?= $category == "Category2"?" selected = 'selected'":"" ?> value="Category2">Categoria2</option>
<option<?= $category == "Category3"?" selected = 'selected'":"" ?> value="Category3">Categoria2</option>
</select>
正确答案是:
<select id="select_category" name="enquiry" >
<option value="Category1" <?php echo $category == "Category1"?" selected = 'selected'":"" ?> >Categoria1</option>
<option value="Category2" <?php echo $category == "Category2"?" selected = 'selected'":"" ?> >Categoria2</option>
<option value="Category3" <?php echo $category == "Category3"?" selected = 'selected'":"" ?> >Categoria2</option>
</select>
