Drupal 7自定义表单在php 7.2中无法使用字符串偏移作为数组错误

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']”行中出现错误：错误：无法将字符串偏移量用作PHP7.2的数组

有人可以帮忙吗？预先感谢。

Answer 1

您必须先声明空数组，然后再分配它

 $form = array();

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

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