I am getting this error, A PHP Error was encountered Severity: Notice
Message: Trying to get property 'post_title' of non-object.
I cannot get the form inputs to print on the page and cannot update. Please help! So, I have tried to update each record and only artist users are able to do that. But I cannot figure out how to show the individual post on the form page. The records saves correctly and deletes but cannot update them.
Controller
function editpost($post_id)//Edit post page
{
if (!$this->session->Role =='member,artist')
{
redirect(base_url() . 'login');
}
$data['success'] = 0;
if( !empty($this->input->post('post_title')) ) {
$data['post_title'] = $this->input->post('post_title');
$data['post'] = $this->input->post('post');
$data['active'] = 1;
/* >> file attach */
View
<form action="<?= base_url()?>starter/editpost/" method="post" class="justify-
content-center" enctype='multipart/form-data'>
<div class="form-group">
<label class="sr-only">Title</label>
<input type="text" class="form-control" placeholder="Title"

</div>
<div class="form-group">
<label class="sr-only">Description</label>
<textarea class="form-control" placeholder="Describe it" name="post" ><?
php echo $post->post; ?></textarea>

<div class="row py-4">

use direct the variable because you are passing just values which you are posting from form.
//like :
//for post_title
<input type="text" class="form-control" placeholder="Title"
name="post_title" value="<?php echo $post_title; ?>">
// for description
textarea class="form-control" placeholder="Describe it" name="post" ><?
php echo $post; ?></textarea>
您不需要在控制器中传递发布数据,您可以在任何地方获取发布数据
<input type="text" class="form-control" placeholder="Title" name="post_title" value="<?php echo ($this->input->post('post_title')!='')?$this->input->post('post_title'):''; ?>">
