Re: best way to determine mobile device - Linux, Apache, MySQL, PHP Discussion Boards

Hi,

I am currentlly using this code to populate news from my database. I want to know how can I make the same paging the result with NEXT and PREVIOUS button?

PHP

<?php
    $conn = mysql_connect('mysql.jassimrahma.com', 'jassimxxxxx', 'xxxxxxx');
    mysql_select_db("jassimrahma", $conn);
    $result = mysql_query("SELECT news_id, news_title, date_format(created_date, '%d %M %Y') as 'news_date' FROM news ORDER BY created_date DESC, news_id DESC", $conn);

    $affected_rows = mysql_num_rows($result);

    echo "<table width='100%' cellpadding='3' cellspacing='3'>";

    while ($i < $affected_rows)
    {
        $news_id = mysql_result($result, $i ,"news_id");
        $news_title = mysql_result($result, $i ,"news_title");
        $created_date = mysql_result($result, $i ,"news_date");

        echo "<tr>";
        echo "<td align='center' valign='top'>";
        echo "<img src='http://www.jassimrahma.com/images/news_arrow.jpg' alt='Jassim.com News' />";
        echo "</td>";
        echo "<td align='left' valign='top'>";
        echo "<a href='http://www.JassimRahma.com/$news_id' target='_blank'>$news_title</a>";
        echo "</td>";
        echo "</tr>";

        $i++;
    }

    echo "<tr><td align='center' valign='top'></td><td align='left' valign='top'><a href='http://www.JassimRahma.com/news' target='_self'><img src='images/more_news.jpg' alt='Technology News - JassimRahma.com' /></a></td></tr>";

Detecting if its a mobile device

Please follow the above link. It looks good

Detecting if its a mobile device
 
Please follow the above link. It looks good

but how can I implement it? Do i have to put it in every page? is it possible to put it in one place for the entire application?

You could do either one of the two.

But I would suggest creating a generic php file with this piece of code in a method. Including that php file in every page and calling that method.

EG:
dection.php <-- contains the check + redirect

Sample index.php:

<?php include_once('detection.php');?>
<!-- rest of document -->

sorry but need more help plz

that mentioned code will be placed in a separet file.. that's file.. but it will be between tage? right? then followed by the if($mobile === true)?

so is the following code correct?:

VB

<?php
    function detect_mobile()
    {
        $_SERVER['ALL_HTTP'] = isset($_SERVER['ALL_HTTP']) ? $_SERVER['ALL_HTTP'] : '';

        $mobile_browser = '0';

        $agent = strtolower($_SERVER['HTTP_USER_AGENT']);

        if(preg_match('/(up.browser|up.link|mmp|symbian|smartphone|midp|wap|phone|iphone|ipad|ipod|android|xoom)/i', $agent))
            $mobile_browser++;

        if((isset($_SERVER['HTTP_ACCEPT'])) and (strpos(strtolower($_SERVER['HTTP_ACCEPT']),'application/vnd.wap.xhtml+xml') !== false))
            $mobile_browser++;

        if(isset($_SERVER['HTTP_X_WAP_PROFILE']))
            $mobile_browser++;

        if(isset($_SERVER['HTTP_PROFILE']))
            $mobile_browser++;

        $mobile_ua = substr($agent,0,4);
        $mobile_agents = array(
                            'w3c ','acs-','alav','alca','amoi','audi','avan','benq','bird','blac',
                            'blaz','brew','cell','cldc','cmd-','dang','doco','eric','hipt','inno',
                            'ipaq','java','jigs','kddi','keji','leno','lg-c','lg-d','lg-g','lge-',
                            'maui','maxo','midp','mits','mmef','mobi','mot-','moto','mwbp','nec-',
                            'newt','noki','oper','palm','pana','pant','phil','play','port','prox',
                            'qwap','sage','sams','sany','sch-','sec-','send','seri','sgh-','shar',
                            'sie-','siem','smal','smar','sony','sph-','symb','t-mo','teli','tim-',
                            'tosh','tsm-','upg1','upsi','vk-v','voda','wap-','wapa','wapi','wapp',
                            'wapr','webc','winw','xda','xda-'
                            );

        if(in_array($mobile_ua, $mobile_agents))
            $mobile_browser++;

        if(strpos(strtolower($_SERVER['ALL_HTTP']), 'operamini') !== false)
            $mobile_browser++;

        // Pre-final check to reset everything if the user is on Windows
        if(strpos($agent, 'windows') !== false)
            $mobile_browser=0;

        // But WP7 is also Windows, with a slightly different characteristic
        if(strpos($agent, 'windows phone') !== false)
            $mobile_browser++;

        if($mobile_browser>0)
            return true;
        else
            return false;
    }

    $mobile = detect_mobile();

    if($mobile === true)
        header('Location: blog');
?>

That would indeed work. If you put the entire function in the external php file and the code below in all files that need the check for mobile devices.

if (detect_mobile()) {
 header('Location: blog');
}

Please note though that the redirect that you put in you code would not work as is. You would need to replace the 'blog' part with a URL to the mobile site.

I am now getting this error:

Parse error: syntax error, unexpected T_VARIABLE in /home/jassimrahma/JassimRahma.com/detection.php on line 4

this is what I put in my index.php 1st line:

C#

<?php
    include_once('detection.php');
    if (detect_mobile()) {
    header('Location: http://m.jassimrahma.com');
    }
?>

and detection.php is here:

VB

<?php
    function detect_mobile()
    {
        $_SERVER['ALL_HTTP'] = isset($_SERVER['ALL_HTTP']) ? $_SERVER['ALL_HTTP'] : '';

        $mobile_browser = '0';

        $agent = strtolower($_SERVER['HTTP_USER_AGENT']);

        if(preg_match('/(up.browser|up.link|mmp|symbian|smartphone|midp|wap|phone|iphone|ipad|ipod|android|xoom)/i', $agent))
            $mobile_browser++;

        if((isset($_SERVER['HTTP_ACCEPT'])) and (strpos(strtolower($_SERVER['HTTP_ACCEPT']),'application/vnd.wap.xhtml+xml') !== false))
            $mobile_browser++;

        if(isset($_SERVER['HTTP_X_WAP_PROFILE']))
            $mobile_browser++;

        if(isset($_SERVER['HTTP_PROFILE']))
            $mobile_browser++;

        $mobile_ua = substr($agent,0,4);
        $mobile_agents = array(

            return true;
        else
            return false;
    }
?>

Thanks

I am using now this and very simple and works fine for me..

http://code.google.com/p/php-mobile-detect/[^]

Put it in the initial page. That is the first page user would open. such as index page or login page.

If it figured out that the client device is mobile save that information to session. As a matter of fact its not a big deal. you dont even need to remember whether it is a mobile device or not. But If the set of functions are different for mobile and pc then you can use the session variable to determine about which function to call.

more over when it would redirect to page allocated for mobile do not put any link to those mobile page that redirect to pc pages

Hi Friends,
I am new to php and i m using xampp server to run php .I am using notepad now .I would like to know is there any editor for php .Also I would like to know is it possible to integrate the editor or tool like netbeans with xamp server.Thanks in advance Smile | :)

There are plenty IDE's and editors out there. You have already said Netbeans. You can also take a look at (1) Notepad++, (2) Aptana, (3) Microsoft Expressions Web, (4) Adobe DreamWeaver, (5) Eclipse. This list is not exhaustive. With the exception of (3) and (4) in my list, the others are free to download and use.
