Question

在我使用PHP从MySQL删除第一张图片之前，我无法上传第二张图片。当我上传图片时，显示的信息是“图片未上传”。在我从MySQL数据库中删除图像之前，会显示此消息。

我的代码：

<?php 
ini_set('mysql.connect_timeout',300);
ini_set('default_socket_timeout',300);
?>
<html>
<body>
<form method="post" enctype="multipart/form-data">
<br/>
    <input type="file" name="image"/>
    <br/><br/>
<input type="submit" name="submit" value ="Upload"/> 
</form>
<?php 
if(isset($_POST['submit'])) {
    if(getimagesize($_FILES['image']['tmp_name'])== FALSE) {
        echo "Please Select an image" ;
    }
    else {
        $image =addslashes($_FILES['image']['tmp_name']);
         $name =addslashes($_FILES['image']['name']);
        $image= file_get_contents($image);
        $image= base64_encode($image);
        saveimage($name,$image);
    }
}
displayimage();
function saveimage($name,$image) {
  $con=mysqli_connect("localhost","***","***");


    mysqli_select_db($con,'images');
    $qry="insert into images(name,image) values ('$name','$image')";
    $result=mysqli_query($con,$qry);
    if($result){
        echo "<br/> Image uploaded.";
    } else {
        echo "<br/> Image not uploaded.";
    }
}
function displayimage ()
{
    $con=mysqli_connect("localhost","***","***");
    mysqli_select_db($con,"images");
    $qry="select * from images";
    $result=mysqli_query($con , $qry);
    while ($row = mysqli_fetch_array($result)) {
        echo '<img height="300" width="300" src = "data:image;base64,'.$row[2].'">';
    }
    mysqli_close($con);
}

?>
