Just contacted PHP modeled a video on a news management system also used in the bootstrap framework
Write down and tidy up your thoughts.
It's a very easy system. The first is to create a database table.
Mysql>create Database Newsdb
Mysql> CREATE TABLE News (
-ID int unsigned NOT NULL Auto_increment primary key,//This is the ID of the news
Title varchar (+) Not null,//This is the headline of the News
-keywords varchar (+) Not null,//This is the news key word
Author varchar (+) Not null,//This is the author of the News.
-Addtime int unsigned not null,//This is the time to join the news
Content text not NULL);//This is the contents of the news
In this way, the database table is built, and the following is the start of writing the page.
First wrote a database configuration file dbconfig.php:
<?php
Define (host, "localhost");//Host Name
Define (USER, "root");//username
Define (PASS, "");//password
Define (DBNAME, "newsdb");//Database name
?>
Then there is a menu.php file
<! DOCTYPE html>After two simple tasks above, it's time to write the homepage index.php:
First of all. Import navigation bar menu.php
<?php include ("index.php"); ?>
And then add a title and a table.
<table class= "Table Table-hover" >
<tr>
<th> News Id</th>
<th> title </th>
<th>keyword</th>
<th> author </th>
<th> Time </th>
<th> content </th>
<th> Operations </th>
</TR>
<?
PHP//Here are 5 parts
1. Import the configuration file
Require ("dbconfig.php");
2. Link MySQL, select database
[Email Protected]_connect (Host,user,pass) or Die ("Link Database error! ");
mysql_select_db (DBNAME, $link);
3. Run the query and return the result set
$sql = "SELECT * from News ORDER by addtime DESC";
$result =mysql_query ($sql, $link);
4. Parse the result set and traverse the output
While ($row =mysql_fetch_assoc ($result)) {
echo "<tr>";
echo "<td>{$row [' id ']}</td>";
echo "<td>{$row [' Tilte ']}</td>";
echo "<td>{$row [' keywords ']}</td>";
echo "<td>{$row [' Author ']}</td>";
echo "<td>{$row [' Addtime ']}</td>";
echo "<td>{$row [' content ']}</td> ';
echo "<td>
<a href= ' # ' > Delete </a>;//here the "#" is just a code name, the back will replace it, because adding and removing operations is more complex, so write a action.php file separately
<a href= ' # ' > Changes </a>;
</td> ";
echo "</tr>"
}
5. Releasing the result set
Mysql_free_result (&result);
Musql_close ($link);
?
>
</table>
action.php:
<?php
This is a page of data deletion and modification
1. Import the configuration file
Require ("dbconfig.php");
2. Link MySQL. and select the database
[Email Protected]_connect (Host,user,pass) or Die ("Database link failed");
mysql_select_db (DBNAME, $link);
3. Depending on the value of the action. To infer the owning operation. Run the corresponding code
Switch ($_get["action"]) {
Case "Add":
1. Access to the information to be added, additional information
$tilte =$_post["title"];
$keywords =$_post["keywords"];
$author =$_post["Author"];
$content =$_post["Content"];
$addtime =time ();
2. Filtering of information
3. Splicing the SQL statement, run the corresponding operation
$sql =insert into News value (NULL, ' ($title) ', ' ($keywords) ', ' ($author) ', $addtime, ' ($content) ');
mysql_query ($sql, $link);
4. Whether the inference is successful
$id =mysql_insert_id ($link);
if ($id >0) {
echo "
}
else{
echo "
}
Echo ("<a href= ' Javascript:window.history.back () ' > Return </a>");
Echo ("<a href= ' index.php ' > Browse News </a>");
Break
Case "Del":
1. Get the news ID you want to delete:
$id =$_get[' id '];
2. Assemble the Delete SQL statement and run the corresponding delete operation
$sql = "Delete from news where id= ($id)";
mysql_query ($sql, $link);
3. After the deletion, I actively jump to the news browsing interface
Header ("location:index.php");
Break
Case "Update":
1. Get the information you want to change
$title = $_post[' title '];
$keywords = $_post[' keywords ');
$author = $_post[' author ');
$content = $_post[' content '];
$id = $_post[' id '];
2. Filter the information to be changed (omitted here)
3. Assemble and change the SQL statement and run the change operation
$sql = "Update news set title= ' ($title) ', keywords= ' ($keywords) ', author= ' ($author) ', content= ' ($content) ' where id= ($id )";
Echo $sql;
mysql_query ($sql, $link);
4. Skip to the Browsing interface
Header ("location:index.php");
Break
}
4. Close the database link
Mysql_close ("$link");
?>
The following page add.php files to join the news:
<?php include ("menu.php");//import navigation bar?
>
<div class= "Container" >
<form action= "Action.php?action=add" method= "POST" >
<table class= "Table table-bordered table-hover table-responsive" >
<tr>
<TD align= "center" > title </td>
<td><input class= "col-xs-10" type= "text" name= "title" ></td>
</tr>
<tr>
<TD align= "center" >keyword</td>
<td><input class= "col-xs-10" type= "text" name= "keywords" ></td>
</tr>
<tr>
<TD align= "center" > Author </td>
<td><input class= "col-xs-10" type= "text" name= "author" ></td>
</tr>
<tr>
<TD valign= "Top" align= "center" > Content </td>
<td><textarea class= "col-xs-10" name= "content" ></textarea></td>
</tr>
<tr>
<TD colspan=2 align= "center" >
<input class= "btn btn-primary" type= "submit" value= "join" >
<input class= "btn btn-primary" type= "reset" value= "reset" >
</td>
</tr>
</table>
</form>
</div>
Then the edited page edit.php page:
<?
php include ("menu.php");//import navigation bar
1. Import the configuration file
Require ("dbconfig.php");
2. Connect to MySQL and select a database
[Email Protected]_connect (Host,user,pass) or Die ("Database link failed");
mysql_select_db (DBNAME, $link);
3. Get the ID of the information you want to change, and assemble to view the SQL statement, run the query, get the information you want to change
$sql = "SELECT * from news where id={$_get[' id '}";
$result =mysql_query ($sql, $link);
4. Infer if you have obtained the information you want to change
if ($result && mysql_num_rows ($result) >0) {
$news =mysql_fetch_assoc ($result);
}else{
Die ("No information is found to be changed");
}
?
;
<form action=" action.php?action=update "method=" post ";
<input type= "hidden" name= "id" value= "<?php echo $news [' id '];?>" >
<table class= "table table-bordered table-hover table-responsive" >
<tr>
<td align= "center" > title </td>
<td><input class= " Col-xs-10 "type=" text "name=" title "Value=" <?
PHP echo $news [' title '];?> "></td>
</tr>
<tr>
<TD align= "center" >keyword</td>
<td><input class= "col-xs-10" type= "text" name= "keywords" value= "<?php echo $news [' keywords '];?>" > </td>
</tr>
<tr>
<TD align= "center" > Author </td>
<td><input class= "col-xs-10" type= "text" name= "author" value= "<?
PHP echo $news [' author '];?
> "></TD>
</tr>
<tr>
<td valign= "Top" align= "Center" > Content </td>
<td><textarea class= "col-xs-10" name= "content" ><?php echo $news [' content '];?
></textarea></td>
</tr>
<tr>
<TD colspan=2 align= "center" >
<input class= "btn btn-primary" type= "Submit" value= "edit" >
<input class= "btn btn-primary" type= "reset" value= "reset" >
</td>
</tr>
</table>
</form>
At last. Mention it. Deleted and Changed "#" with what to replace
Here in order to humanize some, with the JS code to give a hint
<script type= "Text/javascript" >
function Dodel (ID) {
if (Confirm ("OK to delete?")) {
Window.location= "action.php?
Action=del&id= "+ID;
}
}
</script>
First "#", replaced with Javascript:dodel ({$row ["id"]})
A second "#". With edit.php? id={$row ["id"]} override
At this point, a complete PHP news management system is basically complete. Try to improve it tomorrow.
