[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選擇框中選擇值?
在視圖中,我得到這樣的變量,例如:
<?php $category = $itemEditar['Anuncio']['category']; ?>
我需要從選擇框中選擇一個選項:
<select id="select_category" name="enquiry">
<option value="" >selecione</option>
<option value="Category1">Categoria1</option>
<option value="Category2">Categoria2</option>
<option value="Category3">Categoria2</option>
</select>
要進行更新操作,我需要標記數據庫中保存的類別,並且我沒有得到如何執行此操作。
您想要針對每個選項或選項檢查$ category,如果匹配則設置所選屬性。
<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>
正確答案是:
<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>
