I have another question about connecting to Mysql database.
I have a simple text document with Tinymce online text editor. Online I want to change the text with the editor, save it to Mysql database and then show the new text online. I have the following scripts and I get this error from the file doAddContents.php:
Warning: mysql_real_escape_string(): Access denied for user ''@'localhost' (using password: NO) in /../doAddContents.php on line 8
Warning: mysql_real_escape_string(): A link to the server could not be established in /../doAddContents.php on line 8
I have no idea what I'm doing wrong. Here are the scripts:
first the script to connect to the database:
db.php:
<?php
function doDB() {
global $mysqli;
//connect to server and select database
$mysqli = mysqli_connect("localhost", "name", "pass", "db-name");
//if the connection fails, stop script execution
if (mysqli_connect_errno()) {
printf("Connect failed: %s\n", mysqli_connect_error());
exit();
}
}
?>
doAddContents.php file:
<?php
include("db.php");
doDB();
$h4_block = "Contents Saved!";
$elm1 = $_POST['elm1'];
$entity_elm1 = htmlentities($elm1);
$entity_elm1 = mysql_real_escape_string($entity_elm1);
$add_contents_sql = "UPDATE tinymce_contents SET `contents`=
'$entity_elm1', `modified`=now()";
$add_contents_res = mysqli_query($mysqli, $add_contents_sql)
or die(mysqli_error($mysqli));
//close connection to MySQL
mysqli_close($mysqli);
//create nice message for user
$display_block = "<p>The page has been successfully updated.</p>";
?>

View.php file:

include("db.php");

$h4_block = "View Page!";
$get_contents_sql = "SELECT * FROM tinymce_contents";
$get_contents_res = mysqli_query($mysqli, $get_contents_sql)
or die(mysqli_error($mysqli));
if ($get_contents_res = mysqli_query($mysqli, $get_contents_sql)) {
//fetch associative array
while ($row = mysqli_fetch_assoc($get_contents_res)) {
$id = $row['id'];
$contents = $row['contents'];
$modified = $row['modified'];
//Draw the results
$view_block ="<p>ID: ".$id."</p>";
$view_block .="<b>Contents</b>:".html_entity_decode($contents);
$view_block .="<b>Modified</b>:".$modified."<br/>";
}
}
//close connection to MySQL
mysqli_close($mysqli);
?>

According to the documentation of mysql_real_escape_string. The function will try to create a mysql connection if there is no connection opened with mysql_connect()
.
http://php.net/manual/en/function.mysql-real-escape-string.php
You should not be using mysql_real_escape_string()
but mysqli_real_escape_string()
