无法将数据值存储到数据库

Question

我无法将数据存储在MySQL数据库中。 url1数据 - >不会转发到u1.php。

我无法解决这个问题。虽然上运行u1.php这个查询与虚拟阀它是完美的：

mysql_query("UPDATE admins SET url1 = '1234568' WHERE id = '1'"); 

当我检查的DB它是完美的上述价值，但是当我尝试表单数据为url1不工作。

<form action="u1.php" method="post" enctype="multipart/form-data"> 
<label for="file">Select The File:</label> 
<input type="file" name="file" id="file"> 
&nbsp;&nbsp;&nbsp; 
&nbsp;&nbsp; Enter Ad Url :<input type="text" name="url1" id="url1" placeholder="Please Enter Ad Url" width: 500px;> <br><br> 
<input type="submit" name="submit" value="Submit"> 
</form> 

u1.php文件

<?php 

    mysql_connect("localhost","root",""); 
    mysql_select_db("apphp"); 
    mysql_query("UPDATE admins SET url1 = '$url1' WHERE id = '1'"); 




    $allowedExts = array("gif", "jpeg", "jpg", "png"); 
    $temp = explode(".", $_FILES["file"]["name"]); 
    $extension = end($temp); 
    if ((($_FILES["file"]["type"] == "image/gif") 
    || ($_FILES["file"]["type"] == "image/jpeg") 
    || ($_FILES["file"]["type"] == "image/jpg") 
    || ($_FILES["file"]["type"] == "image/pjpeg") 
    || ($_FILES["file"]["type"] == "image/x-png") 
    || ($_FILES["file"]["type"] == "image/png")) 
    && ($_FILES["file"]["size"] < 350000) 
    && in_array($extension, $allowedExts)) 
     { 
     if ($_FILES["file"]["error"] > 0) 
     { 
     echo "Error: " . $_FILES["file"]["error"] . "<br>"; 
     } 
     else 
     { 
     echo "Upload: " . $_FILES["file"]["name"] . "<br>"; 
     echo "Type: " . $_FILES["file"]["type"] . "<br>"; 
     echo "Size: " . ($_FILES["file"]["size"]/1024) . " kB<br>"; 
     move_uploaded_file($_FILES["file"]["tmp_name"], "images/h1.jpg"); 
     echo "Stored in: " . "images/" . $_FILES["file"]["name"]; 

     } 
     } 
    else 
     { 
     echo "Invalid file"; 

    } 
?>

您需要在查询中使用它之前设置$url1。

if (isset($_POST['url1'])) { 
    $url1 = mysql_real_escape_string($_POST['url1']); 
} else { 
    die ("Ad URL is required."); 
} 
mysql_query("UPDATE admins SET url1 = '$url1' WHERE id = '1'");
