function limit_words($string, $word_limit)
{
$words = explode(" ",$string);
return implode(" ",array_splice($words,0,$word_limit));
}

You call the function from your page page with this.

$text = "I wanted to show this function in all its glory and have been able to do this.";
 
echo limit_words($text,7);

This will show the first seven words.

“I wanted to show this function in”

Change the number to whatever suits you.

1. When you develop your excel file save it out as a csv file. This means do not save it as a work book or any other format. When it has been saved take a look at it with a text reader such as notepad or similar. You will probably notice that each column is separated by a comma (,). This is important when we look at importing the file with PHPmyAdmin.

2. Cleanse your CSV file. Get rid of column headings. Ensure that there is an entry of some form in each row and column. Get rid of blank areas.

3. You must ensure that the table you are importing your data into is represented identically in the CSV file. This means that if your table has 10 columns you must have 10 corresponding columns in your CSV file. There is one exception to this however, if your first column is an id autoincrement column this does not need to be one of the included columns in your CSV. For example if you have a table structure like this:

MySql Table: Competitors
id,eventID,imageID,raceNumber,firstName,lastName,raceTime,category,
catPosition,gender,cap

CSV File:
eventID,imageID,raceNumber,firstName,lastName,raceTime,category,
catPosition,gender,cap

The id column is not represented in the CSV file.

4. If you do not have data for some of the columns in the CSV file enter 0 for each line.

5. In PHPmyAdmin click on the import tab. Click on the browse button and select your csv file. It will automatically select the CSV in Format or Imported File area.

6. In the Format of Imported File area:

Fields terminated by ,
Fields enclosed by (leave blank)
Fields escaped by
Lines terminated by auto
Column names eventID,imageID,raceNumber,firstName,lastName,raceTime,category,
catPosition,gender,cap (this is the example above used again here)

7. The category names above are separated by a comma (,) and there are no spaces after or before each word.

8. Click on Go

If everything went well you should have a fully populated table.

$pix .= ("<li><input type="checkbox" name="picture[]" value="'. $root.$dir.' '.$file.'" />
Value One</li>");

The same string with a “Here Doc”.

$pix = <<<END
("<li><input type="checkbox" name="picture[]" value="'. $root.$dir.' '.$file.'" />
Value One</li>")
END;

To use Here Doc you need to start with <<< followed by any word or string of letters, numbers or underscors as long as it does not start with a number. In the example I have used END.

The string must start on a new line after you have started the Here Doc. Variables will be read without he need to put quotes around them.

The end identifier needs to start at the start of a new line and have no white space before it otherwise it will cause an error. You can’t even tab it in. The semicolon is allowable at the end.

 
// Takes the submitted info from the form FOLDER and make variables so we can display images.
            $dir = ($_POST['folder']); //The user selects the relevant folder from a previous form
            $root = 'gallery/';
            $files = scandir("$root$dir");                
 
                   foreach ($files as $file) {
                      if($file =='.'||$file =='..') continue; //get rid of directory dots . ..
                      @$pix .= ("<li><input type="checkbox" name="picture[]" value="". $root.$dir."/".$file."" />
                      <a href="". $root.$dir."/" . $file ."" rel="lightbox[set]">
                      <img src="". $root.$dir."/" . $file ."" alt="".$file.""></a></li>");
                   }

If multiple images were selected an array for picture[] was created. If this was inserted directly into the database only the last item will be stored in the database. So it is necessary to run through the array and insert each item in its own row within the databse. I used another foreach loop for this task. Here is the code.

 
 $name = $_POST['name']; //This is a number for the user 
 $pix = $_POST['picture']; //This is the array of items from the post of the previous script.
 
 
 foreach ($pix as $pic){
 $result=mysql_query("INSERT INTO urls (id, id_key, url, date) VALUES ('', '$name', '$pic', NOW())");
 }

The foreach command will cycle through the array until the last record is reached. Not knowing how many records would be selected this works extremely well.

 
$checkEmail = info@example.com
echo validEmail($checkEmail);

 
function validEmail($email){
 
        // Valid Email address Regular expression
		// No spaces in pattern either
		$pattern='/^S+@S+.S+$/'; 
		if($email && !preg_match($pattern,$email)) {
			$badEmail='The email address does not appear to be correct.';
 
			return $badEmail;
				}
}

You can tweek it to suit your needs.

function validPassword($password) {
        //Empty error array for the errors if any
	$error = array();
		// Password Strength check
		if( strlen($password) < 6 ) {
			$error[] = 'Password need to have at least 6 characters!';
		}
 
		if( strlen($password) > 20 ) {
			$error[] = 'Password needs to have less than 20 characters!';
		}
 
		if( !preg_match("#[0-9]+#", $password) ) {
			$error[] = 'Password must include at least one number!';
		}
 
 
		if( !preg_match("#[a-z]+#", $password) ) {
			$error[] = 'Password must include at least one letter!';
		}
 
 
		if( !preg_match("#[A-Z]+#", $password) ) {
			$error[] = 'Password must include at least one uppercase letter!';
		}
 
				// Make the array readable
				$errors=implode('<br />', $error);
				return $errors;
}

This is how you call it on the relevant page.

// You would give the variable value from the $_POST['Pa55w*rd'] really!!
//This is an example though so here it is simply.
$pw = 'Pa55w*rd';
 
validPassword($pw)

Of course you can change each condition as you see fit and not all conditions need to be kept either. Hope this is useful.

On your page where you call the date from the datbase, put the date into a variable then call the function.

//This is the function
function changeDate($backwardsDate){
	$newDate = date("d-m-Y", strtotime($backwardsDate));
	return $newDate;
}

This is the code on the relevant page.

//Put the date into a variable
$backwardsDate = 2012-10-28;
//Call the function
echo changeDate($backwardsDate);
// Once processed by the function it will output 
// 28-10-2012

This is what goes in the html.

//Define the album date in a variable
$albumDate = 2012-11-01;
//Call to function
albumExpired($albumDate);

This is the function which is called.

                //Change date into a string
		$todaysDate = strtotime($today);
 
                // Change the album date into a string
		$expiryDate = strtotime($expiry);
 
                // compare the two dates (strings)
		if ($expiryDate<$todaysDate){
			return 'Expired';
		}else{
			return 'Not Expired';
		}
}

Remove extra mysql_close statements and this will probably fix it.

Step One

Get the latest version of WordPress from wordpress.org
Unzip the package and add it to the www directory in wamp.

Step Two

Run the activation of WordPress from scratch to make the database and config.php page. Check http://localhost/yoursite/

Step Three

Assuming it is all working locally we can now start to make the conversion. Copy the entire wp-content directory from your working site into your local site files (e.g Delete the local wp-content and replace it with the website version)

Step Four

Open up phpMyAdmin for your live site. Your hosting provider should give you access to this through cpanel or something similar. Open the database that relates to your live site and then click on the Export tab at the top of the page. The default settings are usually fine. Just make sure that you are exporting and sql file. Save it to your desktop where you can easily locate it later. This may take a while depending on the amount of data you have stored.

Step Five

Open phpMyAdmin for your local wamp server. The green W in system tools will allow you to do this quickly. Open the new database that you just created in Step Two. Click on the Structure tab at the top of the page and all the tables within your database will then be displayed. Select all the tables withthe select all link at the bottom or click on each checkbox. Use the drop down menu at the bottom of the tables and select drop. This will delete all the tables that you have in your database on the local server. NOTE: Ensure you are dropping the localhost tables not your live site ones.

Step Six

When your live database download has finished check the size of the file. If it is over 2 megabytes you will have to zip the file in order to allow phpMyAdmin to upload the data. Zip it with you favourite zipping program. If it is still over 2 mb after zipping you will have to make changes to the post_max_size = 8M
upload_max_filesize = 2M
in the php.ini file within wamp. Just ensure that the post_max_size is larger or the same as the upload_max_filesize.

Step Seven

In your local phpMyAdmin while still in the database that you created and have just deleted the files from import the new database information. Click on the import tab and select the sql file or zip file and click on go.

Step Eight

If all went well you will have a whole new set of tables in your new database. In order to be able to access the localhost now click on the wp-options table. The fist entry in the table should be siteurl under the heading of option name. Click on the pencil to edit this. Change the http://yoursite.com to http://localhost/yoursite.

Step Nine

Go to http:/localhost/yoursite/wp-admin/ and log in the same as you would in your live site. When you reach the dashboard check the address bar of the browser to ensure you are in the right site. Go to Settings>General in the dashboard area. Change ‘site address url’ to the same as ‘WordPress Address URL’ e.g. http:/localhost/yoursite.

Step Ten

Check the front end to see if everything is working ok. If you have changed how your permalinks work you may not be able to view pages or posts etc. Go to Settings>Permalinks and select ‘default’ which should rectify any problems.

That is it hope it helps.
