Question

我从textarea插入mysql.i时出现问题，其中包含一个包含多个textarea的表单。form.php

<form name="form1" method="post" action="insert.php">
<thead>
                  <tr>
                    <th>&nbsp;</th>
                    <th>Center Name</th>
                    <th>User Name</th>
                    <th>Password</th>
                    <th>IP Details</th>
                </tr>   
<tr>
                     <td valign="top">1</td>
                     <td valign="top">ABCE</td>
                     <td valign="top">abce</td>
                     <td valign="top">abce123</td>
                     <td valign="top">
                        <textarea rows="4" cols="40"  name="ip_details[]">59.162.181.45,27.251.106.75,59.162.182.155</textarea><br/>
                        </td> 
</tr>   
<tr  class="alt-row">
                     <td valign="top">2</td>
                     <td valign="top">XYZ</td>
                     <td valign="top">xyz</td>
                     <td valign="top">1234</td>
                     <td valign="top">
                        <textarea rows="4" cols="40"  name="ip_details[]">54.23.87.32,198.12.65.64,34.56.43.12</textarea><br/>
                         </td>
                    </tr>

<tr>
                    <td colspan="5" align="center">
<input type="submit" name="submit" id="submit" value="Update" /></td>
                </tr>
</form>

我想将这些数组值插入到数据库中，该数据库将输入ip_details [0]到ABCE行，ip_details [1]到数据库中的XYZ行。当我做的时候

$a=$_POST['ip_details'];

$b= $_POST['ip_details'][0];
echo "$b";

$c= $_POST['ip_details'][1];
echo "$c";

它显示了ABCE和XYZ的ip_details值。

我想在database.id_center（主键）的ipdetails列中添加ip的这些数组值my table structure.show create table table_name

CREATE TABLE `center_listt` (
id_center int(10) NOT NULL AUTO_INCREMENT,
center_name varchar(10) NOT NULL,
user_name varchar(10) NOT NULL,
password varchar(10) NOT NULL,
ipdetails varchar(30) NOT NULL,
PRIMARY KEY (`id_center`)
) ENGINE=InnoDB AUTO_INCREMENT=9 DEFAULT CHARSET=latin1


id_center  center_name  user_name  password  ipdetails
  1         ABCE         abce       1234      59.162.181.45,27.251.106.75,59.162.182.155
  2         XYZ          xyz        1234      54.23.87.32,198.12.65.64,34.56.43.12

我无法找到一种方法来做到这一点。我想做的就是在我的浏览器中回显数组。需要帮助在数据库中插入相同的

        <tr>

                <input type="submit" name="submit" id="submit" value="Update" /></td>
        </tr>
</form>


    <?php

if($_POST){

    $count = count($_POST['row']);

    for($i = 0;$i<$count;$i++){
        $sql = "INSERT INTO TABLE SET field = '{$_POST['row'][$i]}',ip = '{$_POST['ip_details'][$i]}' ";
        echo "<br>".$sql;
    }
}

Answer 2

<?php


if(isset($_POST['submit'])) {
$ip_details = $_POST['ip_details'];
$values = array(
    array('ipdetails' => '"'.$ip_details[0].'"'),
    array('ipdetails' => '"'.$ip_details[1].'"'),
);

$columns = implode(', ', array_keys($values[0]));
foreach($values as $value) {
    $value = implode(',', $value);
    $statement = "INSERT INTO `center_listt` (ipdetails) VALUES ($value) ";
    //echo $statement . "<br/>";
   $res=mysql_query($statement);
    if(!$res) {
        die('could not connect'.mysql_error());
    }
echo "gg";
}
}

列计数dosent匹配第1行的值计数，因为它期望所有数组键都插入mysql insert语句的列表中。

它会运行，但是你所期望的输出如数据库所示，其中已经有一个表有字段值，只是你想在ipdetails列中输入这些ip，它将与id_center匹配。 / p>

它只会插入一个不是你期望发生的新行
