插件组参数到MySQL

Question

我跟着某些线程在这里，但我看不到我在做什么错：

$friends = array 
(
     array("yaron","levi","yaron@gmail.com"), 
     array("david","chohen","david@gmail.com"), 
     array("michal","rubin","michal@gmail.com"), 
     array("dafna","mishal","dafna@gmail.com"), 
     array("tamar","mishal","tamar@gmail.com") 
); 

if(is_array($friends)){ 

    $sql = array(); 
    foreach($friends as $row) { 
       $sql[] = '("'.mysql_real_escape_string($row['firstname']).'","'.mysql_real_escape_string($row['lastname']).'","'.mysql_real_escape_string($row['email']).'")'; 
    } 
    mysql_query('INSERT INTO MyGuests (firstname,lastname,email) VALUES '.implode(',', $sql)); 



} 

Answer 1

你会得到undefined index错误，因为你的数组由firstname没有索引，lastname &等。在imploding过程中也用单引号括起数值。这应该有助于

if(is_array($friends)){ 
    $sql = array(); 
    foreach($friends as $row) { 
     $sql[] = mysql_real_escape_string($row[0]); 
     $sql[] = mysql_real_escape_string($row[1]); 
     $sql[] = mysql_real_escape_string($row[2]); 
     $values = "'".implode("','", $sql)."'"; 
     mysql_query("INSERT INTO MyGuests (firstname,lastname,email) VALUES(".$values.")"); 
    } 
} 

Answer 2

改变你的朋友数组：

$friends = array(
    array("firstname"=>"yaron", "lastname"=>"levi", "email"=>"yaron@gmail.com"), 
    array("firstname"=>"david", "lastname"=>"chohen","email"=>"david@gmail.com"), 
    array("firstname"=>"michal","lastname"=>"rubin", "email"=>"michal@gmail.com"), 
    array("firstname"=>"dafna", "lastname"=>"mishal","email"=>"dafna@gmail.com"), 
    array("firstname"=>"tamar", "lastname"=>"mishal","email"=>"tamar@gmail.com") 
); 

随着这一变化，你的脚本将工作顺利！
