Create a new process using php+ajax

This article mainly introduces the use of php+ajax to create a new process (leave request, purchase, shipment, etc.). Friends in need can refer to it

For managers, the computer-operated leave request process is better than The manual leave process is much more efficient, so how to create a new process?

First of all: What processes need to be clarified?

Secondly: Which personnel are needed to execute each process?

Finally: What is the order of people performing this process?

Step one: Three tables are needed, namely: user table; liucheng table; liuchengjiedian table (the last two have not been added yet)

Step 2: Use thedrop-down listto read the contents of the users table:

 
请选择节点人员:
  query($sql); foreach ($arr as $v){ echo "{$v[2]}"; } ?>   

Implementation effect:

Step 3: Click "Confirm Add" to add the selected person tosession

(1) First introduce the jquery package

(2)ajax code

(3)add-cl.php page

Step 4: List the selected people

(1)Judge first Whether to get the value of session

        

         Copy after login
        
       

(2) After getting the session

else { $arr = $_SESSION["jiedian"]; foreach($arr as $k=>$v) { $sql = "select name from users where uid='{$v}'"; $name = $db->strquery($sql); echo "
{$k}--{$name}-- 
"; } } ?>

(3) Add a click event to the "Remove" button

ajax page:

$(".yichu").click(function(){ var code = $(this).attr("code"); $.ajax({ url:"yichu-cl.php", data:{code:code}, type:"POST", dataType:"TEXT", success:function(data){ window.location.href="main.php" rel="external nofollow" rel="external nofollow" ; } }); })

yichu-cl.php page:

Click to remove Wang Wu: Zhang San and Saturday will remain, and the codes will be rearranged

The last step: add a save button and add the data to Database

Note: All data before this exists in the session

(1) Add process name input box and save button

 请输入流程名称：   

(2) Click Save button to store all information in the database

ajax code

$(".baocun").click(function(){ var name = $(".name").val(); // alert(name); $.ajax({ url:"baocun-cl.php", data:{name:name}, type:"POST", dataType:"TEXT", success:function(data){ alert("保存成功！"); } }); })

baocun-cl.php page

query($sql,0); //将数据写入liucehngjiedian表 $arr = $_SESSION["jiedian"]; foreach($arr as $k=>$v) { $sql = "insert into liuchengjiedian values ('','{$code}','{$v}','{$k}')"; $db->query($sql,0); } ?>

Implementation effect and data written to the database:

At this step, the entire Liu Xinjian process steps can be realized, and the interface can be beautified a little later~~~~

Summary: Each step of the processing page is more important; sessoin accesses data; unsettle() removes the array; array_values() rearranges the array, etc.~~~
