Below specified basic pagination in PHP with MySQL

<?php
$cou_per_page=10;
mysql_connect(‘localhost’,’root’,”);
mysql_select_db(‘pagination’);
if (isset($_GET[“page”])) { $page = $_GET[“page”]; } else { $page=1; };
$start_page = ($page-1) * $cou_per_page;
$sql = “SELECT * FROM page_table LIMIT $start_page, $cou_per_page”;
$rs_result = mysql_query ($sql); //run the query
?>
<table>
<tr><td>Name</td><td>Address</td></tr>
<?php
while ($row = mysql_fetch_assoc($rs_result)) {
?>
<tr>
<td><?php echo $row[‘page_name’]; ?></td>
<td><?php echo $row[‘page_add’]; ?></td>
</tr>
<?php
};
?>
</table>
<?php
$sql = “SELECT * FROM page_table”;
$rs_result = mysql_query($sql); //run the query
$total_records = mysql_num_rows($rs_result); //count number of records
$total_pages = ceil($total_records / $cou_per_page);

echo “<a href=’?page=1′>”.’|<‘.”</a> “; // Goto 1st page

for ($i=1; $i<=$total_pages; $i++) {
echo “<a href=’?page=”.$i.”‘>”.$i.”</a> “;
};
echo “<a href=’?page=$total_pages’>”.’>|’.”</a> “; // Goto last page
?>

Install drupal through command line step by step

Posted by

Download and extract files

$  wget https://www.drupal.org/files/projects/drupal-x.x.tar.gz
$  tar -zxvf drupal-x.x.tar.gz

Move to root folder

$  mv drupal-x.x /var/www/html

Create the configuration file and grant permissions

In the sites/default directory, copy the default.settings.php file and rename the copied file to settings.php.

$ cp sites/default/default.settings.php sites/default/settings.php

Give the web server write privileges (666 or u=rw,g=rw,o=rw) to the configuration file.

$ chmod a+w sites/default/settings.php

Give the web server write privileges to the sites/default directory.

$ chmod a+w sites/default

Create the Drupal database

To complete the installation, you must create an empty database and a user with full access to the newly created database for Drupal to use. You can do this by command line, or through phpMyAdmin or another database client.

$ mysqladmin -u username -p create databasename

Where ‘username’ is a MySQL user which has the CREATE and GRANT privileges. MySQL will prompt for the ‘username’ database password. Next you must set the access database rights. Log in to MySQL:

$ mysql -u username -p

$ GRANT SELECT, INSERT, UPDATE, DELETE, CREATE, DROP, INDEX, ALTER, CREATE TEMPORARY TABLES, LOCK TABLES ON databasename.* TO ‘username’@’localhost’ IDENTIFIED BY ‘password’;

Run the installation script

Point your browser to the base URL of your website

Create an .info.yml file in Drupal 8

Posted by

0

You create the .info.yml file in the root of your theme folder. The folder should have the same name as the .info.yml file. So if your theme is named “Fluffiness” then the folder is named “fluffiness/” and the .info.yml file is named “fluffiness/fluffiness.info.yml“. If the file is present your theme will be visible in your website at Manage > Appearance (http://example.com/admin/appearance).

Example

name: Fluffiness (Required)
type: theme (Required)
description: ‘A cuddly theme that offers extra fluffiness.’ (Required)
package: Custom
core: 8.x (Required)
libraries:
– fluffiness/global-styling
stylesheets-remove:
– ‘@classy/css/layout.css’
– core/assets/vendor/normalize-css/normalize.css
regions:
header: Header
content: Content
sidebar_first: ‘Sidebar first’
footer: Footer

jQuery the noConflict() Method

Posted by

0

jQuery and Other JavaScript Frameworks
As you already know; jQuery uses the $ sign as a shortcut for jQuery.

There are many other popular JavaScript frameworks like: Angular, Backbone, Ember, Knockout, and more.

What if other JavaScript frameworks also use the $ sign as a shortcut?

If two different frameworks are using the same shortcut, one of them might stop working.

The jQuery team have already thought about this, and implemented the noConflict() method.

The jQuery noConflict() Method
The noConflict() method releases the hold on the $ shortcut identifier, so that other scripts can use it.

Examples:

$.noConflict();
jQuery(document).ready(function(){
jQuery(“button”).click(function(){
jQuery(“p”).text(“jQuery is still working!”);
});
});

var jq = $.noConflict();
jq(document).ready(function(){
jq(“button”).click(function(){
jq(“p”).text(“jQuery is still working!”);
});
});

jQuery Set Content and Attributes

Posted by

0

  1. text() – Sets or returns the text content of selected elements
  2. html() – Sets or returns the content of selected elements (including HTML markup)
  3. val() – Sets or returns the value of form fields

$(“#btn1”).click(function(){
$(“#test1”).text(“Hello world!”);
});
$(“#btn2”).click(function(){
$(“#test2”).html(“<b>Hello world!</b>”);
});
$(“#btn3”).click(function(){
$(“#test3”).val(“Dolly Duck”);
});

The jQuery attr() method is also used to set/change attribute values.

$(“button”).click(function(){
$(“#w3s”).attr(“href”, “http://www.w3schools.com/jquery&#8221;);
});

$(“#w3s”).attr({
“href” : “http://www.w3schools.com/jquery&#8221;,
“title” : “W3Schools jQuery Tutorial”
});
