Question

我在选择下拉菜单中使用多个选择，我想将其存储在数据库中。

我听说内爆爆炸，但我不知道如何使用它们。请告诉我如何在codeigniter中内爆和爆炸。

我的HTML表单：

<div class="form-group">
    <label>
        Please Select Proof Of ID Deposit
    </label>
    <select multiple="" name="oids" class="js-example-basic-multiple js-states form-control">
        <optgroup>
            <option value="Passport">Passport</option>
            <option value="National ID Card">National ID Card</option>
            <option value="Driving Licence">Driving Licence</option>
            <option value="Univesity ID">Univesity ID</option>
        </optgroup>
    </select>
</div>

我的控制器：

public function customer_insert(){
    $data = array(
        'id'=>$this->input->post('up_id'),
        'Other_id'=>$this->input->post('oids') //here I want to implode my values
    )
    $this->db->insert('customer', $data);
}

查看文件：

<table>
    <thead>
        <tr><td>ID</td></tr>
        <tr><td>Other ID</td></tr>
    </thead>
<?php foreach ($query as $customer){?>
    <tr><td><?php echo $customer->id?></td></tr>
    <tr><td><?php echo $customer->Other_id?></td></tr> // I want to show my imploded value here. 
<?php}?>
</table>

Answer 1

首先在您的 HTML FORM 中，您需要使用数组更改name attr值，除非它不会生成所选值的数组

<select multiple="" name="oids" class="js-example-basic-multiple js-states form-control">

必须像

<select multiple="" name="oids[]" class="js-example-basic-multiple js-states form-control">

在控制器功能

中

public function customer_insert() {

    $oidVal = implode(",", $this->input->post('oids'));// Converted array into comma separated value using implode

    $data = array(
        'id'=> $this->input->post('up_id'),
        'Other_id'=> $oidVal
    )
    $this->db->insert('customer', $data);
}

并在查看文件

中

<table>
    <thead>
        <tr><td>ID</td></tr>
        <tr><td>Other ID</td></tr>
    </thead>
<?php foreach ($query as $key => $value) { ?>
    <tr><td><?php echo $value['id']; ?></td></tr>
    <tr><td><?php echo explode(',',$value['Other_id']);?></td></tr> // exploded value
<?php } ?>
</table>

Answer 2

您可以使用implode函数通过字符串和explode函数连接数组元素，以按字符串分割字符串。在这种情况下，您可以像这样使用它们。

public function customer_insert() {
    // Convert array to comma separated value 
    $oidString = implode(",", $this->input->post('oids'));
    $data = array(
        'id'=> $this->input->post('up_id'),
        'Other_id'=> $oidString //here I want to implode my values
    )
    $this->db->insert('customer', $data);
}

如果要从逗号分隔值中取回数组，可以使用explode。

// Convert comma separated value to array
$otherId = explode(",", $customer->Other_id);

希望它对你有用。

Answer 3

 public function insert()
 {
//Insert second stage details for employer into database.
$Specilized_category = $this->input->post('spec_cat');
$data=array(
'Specilized_category'=>json_encode(implode(",", $Specilized_category)),
 );
$this->db->insert('tbl_employer', $data);

implode在codeigniter中爆炸数据
