Front-End Interaction summary 2: Uploading form data using PHP

1: Upload a form using PHP

1.1 Data collection for form form forms

HTML page:

Code explanation: The core module is the property of the form:

-- How to submit: method= "POST" -- Specify the Name property : For example name= "username"-- Specify file upload format for form : enctype= "Multipart/form-data" 2 Click the Submit button after the background action

2.1 Get the image data by $_files the Hyper global variable:

Two-dimensional array, you can get the content of the submission data uploaded by the form.

  Array  (      [PHOTO] = array          (              [name] + picture.jpg   file name              [Type] = = Image/jpeg     File Type              [Tmp_name] = C:\Users\Jepson\AppData\Local\Temp\phpBF97.tmp  temporarily stored path              [ERROR] = 0    error code, if 0 Indicates no error              [size] = 17552  file size, unit byte 17kb or so)  

2.2 PHP Image dump:

  //1 Getting an array of files  $file=$_files[' Photo ']; if($file[' error '] = = = 0) {//2 need to dump files    $ftmp=$file[' Tmp_name '];//3 Get temporary file path//4 intercept suffix name    $name=$file[' Name '];//source file name 1.gif    $ext=STRRCHR($name, "." );//. gif//5 randomly generated file name    $newName= Time().Rand(10000, 99999).$ext; //move_uploaded_file ("Temporary File path", "Store file path")//6 dump file    Move_uploaded_file($ftmp, "./upload/".$newName );
}

2.3 by $_post Super global variable gets post data, saved in global variable.

   $username  = $_post  [' username '  ];   $nickname  = $_post  [' nickname '  Span style= "COLOR: #000000" >);   $age  = $_post  [' Age ' );   $photo  = ""; //  picture address   

2.4 Preparing the SQL statement for database write operations

Inserting data

$sql = "insert into Stu (name, nickname, age, tel, sex, photo, classid)          values ('$username  ', '$nickname$age, '$tel', '$sex', '$photo$class )";

2.5 Determine if the insert succeeds and jump action

if $sql )     {echo "add Success";     // Jump to Student list php file    Header (' location:studentList.php ');  }   Else {    echo "add failed";  }

Note: my_exec ($sql)--php executes the SQL statement.
