Question

我想从控制器发送的视图中的flashdata数组中获取单个值。

控制器：

        $post=array(
            'author_id'=>$this->input->post('author'),
            'title'=>$this->input->post('post_title'),
            'subtitle'=>$this->input->post('post_subtitle'),          
            'post'=>$this->input->post('textarea1'), 
            'image'=>$this->upload->file_name,          
        );

        $this->session->set_flashdata('postdata',$post);

视图

<?php var_dump($this->session->flashdata('postdata'))?>

上面的结果给了我以下结果。

array（5）{[“” author_id“] => string（1）” 6“ [” title“] => string（3）” uyk“ [” subtitle“] => string（26）” Full- Stack Web开发“ [” post“] =>字符串（1）” u“ [” image“] =>字符串（0）”“}

如何仅获得标题或副标题之类的单个值？

这个with tf.Session() as test: tf.set_random_seed(1) y_true = (None, None, None) y_pred = (tf.random_normal([3, 128], mean=6, stddev=0.1, seed = 1), tf.random_normal([3, 128], mean=1, stddev=1, seed = 1), tf.random_normal([3, 128], mean=3, stddev=4, seed = 1)) loss = triplet_loss(y_true, y_pred) print("loss = " + str(loss.eval()))
