我已经创建了一个表格,通过结构 1. field_dimensions from physcial模块。 2.然后添加图像字段field_image 3.通过form_alter添加ajax按钮。下面提Drupal7:通过按下其他ajax按钮阻止图片上传
$form['getquote_fs']['getquote']['get-quote-btn'] = array(
'#type' => 'button',
'#name' => 'estimate',
'#button_type' => 'button',
'#executes_submit_handler' => false,
'#limit_validation_errors' => array(array('field_dimensions')),
'#size' => 5,
'#weight' => 100,
'#default_value' => '<span class="bold sd-red">get</span> <span class="normal sd-orange">estimate</span>',
'#maxlength' => 5,
'#description' => t('an industry estimate of how much would I pay.'),
'#ajax' => array(
'callback' => 'custom_startrack_ajax_cal',
'method' => 'replace',
'prevent'=> 'sumbit',
),
);
现在,当表单内,如果我浏览图像,然后按任一其他Ajax button.Its直接上传image.How我可以被上传的文件夹中删除它
我已经试过这..its不工作 –
