Question

我遇到此错误：

PDOStatement :: execute（）期望参数1为数组，给定字符串在第63行的C：\ xampp \ htdocs \ Work \ AppDarbNajah \ App \ Database.php中

ArticleController代码：

public function edit() {
        $id = $_GET['ID'];
        if(!empty($_POST) && (!empty($_FILES))){

           $this->Article->update($id, [
                 'ref' => $_POST['ref'],
                 'desig' => $_POST['desig'],
                 'category_id' => $_POST['category_id'],
                 'tva' => $_POST['tva'],
                 'unit_id' => $_POST['unit_id'],
                 'Supplier_id' => $_POST['box-infos-id'],
                 'thumb' => $_FILES['thumb']['name'],
                 'created_by' => 2855,
                 'updated_by' => 2855
              ]);
        }
        $categories = $this->Category->extract('ID', 'category');
        $units = $this->Unit->extract('ID', 'unit');
        $tva = $this->Tva->extract('ID', 'tva (%)');
        $article = $this->Article->find($id);
        var_dump($article);
        $form = new BootstrapForm($article);
        $this->render('articles/edit',compact('form', 'categories', 'units', 'tva'));
     }

第63行是：

'ref' => $_POST['ref']

我没有编写所有代码，而只编写了有错误的函数

更新功能代码：

public function update($id, $fields){
     $sql_pairs = [];
     $attributes = [];
     foreach ($fields as $k =>$v){
        $sql_pairs[] = "$k = ?";
        $attributes[] = $v;
     }
     $attributes = [];
     $sql_parts = implode(', ', $sql_pairs);
     $this->query("UPDATE INTO {$this->table} SET $sql_parts WHERE ID = ?", $attributes);
  }

Answer 1

问题是我应该在查找函数中使用数组[$ id]如下：

public function find($id){
     return $this->query("SELECT * FROM {$this->table} WHERE ID = ?", [$id], true); 
  }

Answer 2

我不确定您用于创建模型的库，但是您的功能很奇怪。

public function update($id, $fields){
     $sql_pairs = [];
     $attributes = [];
     // this bring an idea that you create list of fields to update  #ref1
     foreach ($fields as $k =>$v){
        $sql_pairs[] = "$k = ?";
        // here you add new value for next field to attributes #ref2
        $attributes[] = $v;
     }
     // here you reset all values collected (#ref2) #ref3
     // $attributes = []; //so let remove it
     // but instead we need to add ID value to our query
     $attributes[] = $id;
     $sql_parts = implode(', ', $sql_pairs);
     // UPDATE for MySQL should be something like :
     // UPDATE my_table SET col1="newval1", col2="newval2" WHERE ID = 1
     // lets try to get that format 

     $this->query("UPDATE {$this->table} SET $sql_parts WHERE ID = ?", $attributes);
  }

希望现在它将更好。...
