图片消失怎么解决
图片消失如何解决
先是图片文件上传
$file=$_FILES['userfile'];
if(is_uploaded_file($file['tmp_name'])){
$query=mysql_query("INSERT INTO gdb_banner(image_src ) VALUES ('images/{$file['name']}*{$_PO['myselect']}')");
if($query){
echo "";
} else{
echo "<script>alert('临时文件夹找不到上传的文件');history.back();</script>";
exit();
}
}这步是正确的,下面 在页面显示
$query=mysql_query("SELECT id,image_src FROM gdb_banner ORDER BY id DESC");
$result=mysql_fetch_array($query,MYSQL_ASSOC);
$src=explode('*',$result['image_src']);
if($src[1]=="left"){
$srcleft=$src[0];
} else {
$srcright=$src[0];
}
?>
左面
右面
$_PO['myselect'] 是上传左面还是右面的参数
每当我上传了左面,右面的图片就不见了,当我上传了右面,左面的图片就没了,如何让两个图片在一起
------解决方案--------------------
$src=explode('*',$result['image_src']);
if($src[1]=="left"){
$srcleft=$src[0];
} else {
$srcright=$src[0];
}
这里有问题,最后的结果就是图片路径变量只有一个存在,要么是 $srcleft 或者 $srcright;正确的方法是你读出的数据应该有两条,一条是 $srcleft ; 一条是 $srcright 的
------解决方案--------------------
if($src[1]=="left"){
$srcleft=$src[0];
} else {
$srcright=$src[0];
}
只有一个变量被赋值。当你上传左边时,你可以用firebug察看右边图片的src地址。估计为空。

MySQL is suitable for beginners because it is simple to install, powerful and easy to manage data. 1. Simple installation and configuration, suitable for a variety of operating systems. 2. Support basic operations such as creating databases and tables, inserting, querying, updating and deleting data. 3. Provide advanced functions such as JOIN operations and subqueries. 4. Performance can be improved through indexing, query optimization and table partitioning. 5. Support backup, recovery and security measures to ensure data security and consistency.

Navicat itself does not store the database password, and can only retrieve the encrypted password. Solution: 1. Check the password manager; 2. Check Navicat's "Remember Password" function; 3. Reset the database password; 4. Contact the database administrator.

Create a database using Navicat Premium: Connect to the database server and enter the connection parameters. Right-click on the server and select Create Database. Enter the name of the new database and the specified character set and collation. Connect to the new database and create the table in the Object Browser. Right-click on the table and select Insert Data to insert the data.

MySQL is an open source relational database management system. 1) Create database and tables: Use the CREATEDATABASE and CREATETABLE commands. 2) Basic operations: INSERT, UPDATE, DELETE and SELECT. 3) Advanced operations: JOIN, subquery and transaction processing. 4) Debugging skills: Check syntax, data type and permissions. 5) Optimization suggestions: Use indexes, avoid SELECT* and use transactions.

Navicat for MariaDB cannot view the database password directly because the password is stored in encrypted form. To ensure the database security, there are three ways to reset your password: reset your password through Navicat and set a complex password. View the configuration file (not recommended, high risk). Use system command line tools (not recommended, you need to be proficient in command line tools).

Steps to perform SQL in Navicat: Connect to the database. Create a SQL Editor window. Write SQL queries or scripts. Click the Run button to execute a query or script. View the results (if the query is executed).

You can create a new MySQL connection in Navicat by following the steps: Open the application and select New Connection (Ctrl N). Select "MySQL" as the connection type. Enter the hostname/IP address, port, username, and password. (Optional) Configure advanced options. Save the connection and enter the connection name.

MySQL and SQL are essential skills for developers. 1.MySQL is an open source relational database management system, and SQL is the standard language used to manage and operate databases. 2.MySQL supports multiple storage engines through efficient data storage and retrieval functions, and SQL completes complex data operations through simple statements. 3. Examples of usage include basic queries and advanced queries, such as filtering and sorting by condition. 4. Common errors include syntax errors and performance issues, which can be optimized by checking SQL statements and using EXPLAIN commands. 5. Performance optimization techniques include using indexes, avoiding full table scanning, optimizing JOIN operations and improving code readability.
