Drupal 7 自定义表单无法将字符串偏移量用作 php 7.2 的数组错误

Question

我有一个自定义的 drupal 7 表单，如下所示

   $form['general_details'] = array(
         '#type' => 'fieldset',
         '#title' => t('General'),
         '#description' => t('General Information.'),
         '#required' => TRUE,
         );

   $form['general_details']['salutation'] = array(
         '#type' => 'select',....

我在“$form['general_details']['salutation']”行中收到错误错误：无法将字符串偏移量用作数组 PHP7.2

有人可以帮忙吗？提前致谢。

Answer 1

你必须在赋值之前声明空数组

 $form = array();

$form['general_details'] = array(
         '#type' => 'fieldset',
         '#title' => t('General'),
         '#description' => t('General Information.'),
         '#required' => TRUE,
);

$form['general_details']['salutation'] = array(
         '#type' => 'select',....
