可能重复：
PHP SQL Form Insert

我创建了一个表单来获取输入并将它们插入表中。它不是在表“employee”中插入值，而是仅插入密码;这也是数据库管理员。该怎么办？？其他字段留空。任何帮助都会很棒。

<?php
    //include the connection file

    require_once('connection.php');
    require_once("validation.php");

    if( isset($_POST['send']) && (!validateName($_POST['name']) || !validateEmail($_POST['email']) || !validatePasswords($_POST['pass1'], $_POST['pass2']) || !validateContact($_POST['contact']) || !validateAge($_POST['age'])) ):?>
                <div id="error">    
                    <ul>
                        <?php if(!validateName($_POST['name'])):?>
                            <li><strong>Invalid Name:</strong> We want names with more than 3 letters.</li>
                        <?php endif?>
                        <?php if(!validateEmail($_POST['email'])):?>
                            <li><strong>Invalid E-mail:</strong> Type a valid e-mail please.</li>
                        <?php endif?>
                        <?php if(!validatePasswords($_POST['pass1'], $_POST['pass2'])):?>
                            <li><strong>Passwords are invalid:</strong> Passwords doesnt match or are invalid!</li>
                        <?php endif?>
                        <?php if(!validateContact($_POST['contact'])):?>
                            <li><strong>Please enter your contact number.</strong></li>
                        <?php endif?>
                        <?php if(!validateAge($_POST['age'])):?>
                            <li><strong>Please enter your age</strong></li>
                        <?php endif?>

                    $query .= "('$name', '$password', '$email','$contact','$age','$gender','$location','$skill')";
                    // run the query

重复的问题......这是安南的回答：

我为你写了一个完整的代码：

<form action="<?php echo $editFormAction; ?>" method="post" name="form1" id="form1">
  <table align="center">
  <tr valign="baseline">
  <td nowrap="nowrap" align="right">Name:</td>
  <td><input type="text" name="name" value="" size="32" /></td>
</tr>
<tr valign="baseline">
  <td nowrap="nowrap" align="right">Email:</td>
  <td><input type="text" name="email" value="" size="32" /></td>
</tr>
<tr valign="baseline">
  <td nowrap="nowrap" align="right">Pass1:</td>
  <td><input type="text" name="pass1" value="" size="32" /></td>
</tr>
<tr valign="baseline">

                   GetSQLValueString($_POST['id'], "int"),

                   GetSQLValueString($_POST['age'], "text"));

mysql_select_db($database_yourdatabase, $databasename);

$insertGoTo .= (strpos($insertGoTo, '?')) ? "&" : "?";
$insertGoTo .= $_SERVER['QUERY_STRING'];
}
header(sprintf("Location: %s", $insertGoTo));
}

mysql_select_db($database_yourdatabase, $databasename);
$query_query = "SELECT * FROM employee";
$query = mysql_query($query_query, $databasename) or die(mysql_error());
$row_query = mysql_fetch_assoc($query);
$totalRows_query = mysql_num_rows($query);

mysql_free_result($query);
?>

希望它有所帮助！

试试这个，你必须使用mysql_real_escape_string来防止sql注入......

   <?php
      //include the connection file

      require_once('connection.php');
      require_once("validation.php");

if( isset($_POST['send']) && (!validateName($_POST['name']) || !validateEmail($_POST['email']) || !validatePasswords($_POST['pass1'], $_POST['pass2']) || !validateContact($_POST['contact']) || !validateAge($_POST['age'])) ):?>
            <div id="error">    
                <ul>
                    <?php if(!validateName($_POST['name'])):?>
                        <li><strong>Invalid Name:</strong> We want names with more than 3 letters.</li>

                    <?php if(!validateEmail($_POST['email'])):?>
