[英]How to save data in JSON format using CodeIgniter?
I have a value and the second one is the model part which is used for storing the data in JSON format.我有一个值,第二个是用于以 JSON 格式存储数据的模型部分。 Here
spam_management
is the column in the table in that I have to store like [{delete:30}]
.这里
spam_management
是表中的列,我必须像[{delete:30}]
一样存储。 30
is the value taken from the selected option. 30
是取自所选选项的值。 How can I do that?我怎样才能做到这一点?
public function update_selectedspmlds()
{
$value = $this->input->post("value");
$this->approval_model->update_selectedspmlds($value);
}
public function update_selectedspmlds($value)
{
$myJson = '{
"delete": [{
"lastName": '.$value.'
}]
}';
$this->db->insert('pm1cti_details', ['spam_management' => $myJson]);
}
In order to create a JSON and store like [{delete:30}]
.为了创建一个 JSON 并像
[{delete:30}]
一样存储。 You need to save the value in a nested array and create a JSON by json_encode
before saving it to the DB.您需要将值保存在嵌套数组中,并在将其保存到数据库之前通过
json_encode
创建一个 JSON。
public function update_selectedspmlds($value) {
$myArray = array(
array(
'delete' => 30
)
);
$myJson = json_encode($myJson);
$this->db->insert('pm1cti_details', ['spam_management' => $myJson]);
}
