    Dyslexic and just cant get this right... HELP PLEASE

    in Third Party Scripts

    Posted

    Ok so i have been playing with my site for a while and getting there very slowly... but heres the rub i am DYSLEXIC and am having issues following a tutorial and the code therein... the tutorial / code is over at http://www.scriptplayground.com/tutorials/php/Tag-Cloud/ and  where i am at is

    [code]
    <html>
    <head>
    <style type="text/css">
    .tag_cloud { padding: 3px; text-decoration: none; }
    .tag_cloud:link  { color: #81d601; }
    .tag_cloud:visited { color: #019c05; }
    .tag_cloud:hover { color: #ffffff; background: #69da03; }
    .tag_cloud:active { color: #ffffff; background: #ACFC65; }
    </style>
    </head>

    <body>
    <?php
    function get_tag_data() {
    $host = "localhost";
    $dbname = "###";
    $dbuser = "###";
    $dbpass = "###";

    $connection = mysql_connect($host, $dbuser, $dbpass) or die(mysql_error());
    $db = mysql_select_db($dbname) or die(mysql_error());

      $result = mysql_query("SELECT uid ,firstname ,lastname FROM user ORDER BY uid DESC limit 20");
      while($row = mysql_fetch_array($result)) {
        $arr[$row['firstname, lastname']] = $row['count'];
      }
      ksort($arr);
      return $arr;
    }

    function get_tag_cloud() {

    $min_font_size = 100%;
    $max_font_size = 250$;

    $tags = get_tag_data();
    $minimum_count = min(array_values($tags));
    $maximum_count = max(array_values($tags));
    $spread = $maximum_count - $minimum_count;

    if($spread == 0) {
        $spread = 1;
    }

    $cloud_html = '';
    $cloud_tags = array(); // create an array to hold tag code
    foreach ($tags as $tag => $count) {
    $size = $min_font_size + ($count - $minimum_count)
    * ($max_font_size - $min_font_size) / $spread;
    $cloud_tags[] = '<a style="font-size: '. floor($size) . 'px'
    . '" class="tag_cloud" href="http://www.mouse.nodstrum.com/full_profile?u$uid . '" title="\'' . $firstname $lastname . '\' profile">'
    . htmlspecialchars(stripslashes($tag)) . '</a>';
    }
    $cloud_html = join("\n", $cloud_tags) . "\n";
    return $cloud_html;

    ?>

    //Here is some example HTML to call this tag builder.
    <h3>Sample Tag Cloud results</h3>
    <div id="wrapper"
    <!-- BEGIN Tag Cloud -->
    <?php print get_tag_cloud(); ?>
    <!-- END Tag Cloud -->
    </div>

    </body>
    </html>
    [/code]

    [SOLVED] My first SQL trial... but where am i going wrong?

    My first SQL trial... but where am i going wrong?

    [Code]

    <?php // connect to database
    $host = "localhost";
    $dbname = "###"; $dbuser = "###";
    $dbpass = "###";
    $connection = mysql_connect($host, $dbuser, $dbpass) or die(mysql_error()); $db = mysql_select_db($dbname) or die(mysql_error());
    // Bah Humbug! i will have this work!!!
    $max = mysql_query("SELECT MAX(uid) FROM user") or die ("nope. Didn't work...!");
    echo $max;
    ?>
    [/Code]


    Ok so this is my first SQL trial... but where am i going wrong? i get the message "Resource id #3" where i was expecting to see "14"

    Tables within DB: if table is populated then do this...

    in PHP Coding Help

    Posted

    I have a problem, which I am sure is easy enough to work out but hey, if only my PHP skills were better!

    Problem. Have a look at my member profile page [http://mouse.nodstrum.com/full_profile.php?u=11], in the top right hand corner is the “Tim’s Time With Disney” box… I want to add the content dynamically.

    In the Database there are six relevant tables, A, B, C, D, E, and F and each of them has the following contents:
    [code]
        # Dump of table A
        `did` int(9) NOT NULL auto_increment,
        `uid` int(9) NOT NULL default '0',
        `start` int(4) NOT NULL default '0',
        `finish` int(4) NOT NULL default '0',
        `Job1` int(1) NOT NULL default '0',
        `Job2` int(1) NOT NULL default '0',
        `Job3` int(1) NOT NULL default '0',
        `Job4` int(1) NOT NULL default '0',
        `Job5` int(1) NOT NULL default '0',
        PRIMARY KEY (`did`)
        ) TYPE=MyISAM;
    [/code]

    What I (think I) am aiming to do is roughly…
    Look in table a >> are there values in ‘Start’ and ‘finish’ >> if so, then put in the right logo >> on the next line echo $start & $finish >> list the ‘jobs’ where there is a ‘1’ not a ‘0’ >> move on to the next table and repeat.

    If a PHP guru type could give me a pointer or two I’ll go on to do the rest.

    As I have said before, I hate asking for code, but as a dyslexic learning to write new stuff is a bugger and I need a few pointers.

    Many thanks

    reversing text...

    in PHP Coding Help

    Posted

    I have been using a language filter to add tooltips (informative mousovers) to my site but I had an issue with the filter finding keywords within the added mousover script… erm… a little clearer? Well if I used “Duck” as a keyword and then I put the phrase “Donald Duck” into the mouesover explanation the function died so I tried this…

    I reversed all the content with
    [code]
    <?php
    $outputtext = strrev($inputtext);
    echo $outputtext
    ?>
    [/code]

    So “Donald ‘Fauntleroy’ Duck He usually wears a sailor shirt and cap — but no pants (except when he goes swimming). Although usually easygoing, Donald's most famous trait is his short and often explosive temper. Donald's famous voice, and semi-intelligible is one of the most identifiable voices in the world”

    Became

    “dlrow eht ni seciov elbaifitnedi tsom eht fo eno si elbigilletni-imes dna ,eciov suomaf sdlanoD .repmet evisolpxe netfo dna trohs sih si tiart suomaf tsom sdlanoD ,gniogysae yllausu hguohtlA .)gnimmiws seog eh nehw tpecxe( stnap on tub — pac dna trihs rolias a sraew yllausu eH kcuD yoreltnuaF dlanoD”

    then I used a little CSS to put it right again…

    [code]
    .backwards {unicode-bidi:bidi-override; direction: rtl;}
    [/code]

    Well I thought so… but have a look for yourself what happens… http://mouse.nodstrum.com/backwards.php

    Any ideas??? Please

    Better rude word filter... when they change le++er5 for characters

    in PHP Coding Help

    Posted

    Shoz, thank you very much for all your assistance on the bad word filter. It is much appreciated!

    I think you’re on to a good thing with the switchable filter, It’ll preserve personal expression and peoples sensibilities. So yes… and the false positives would become a null issue.

    For my part I have been working on the bad words array/list. (I don’t have php on my works laptop.) I was also thinking that as a combined project it should be posted on the site for use by all… what would you say?

    Again, many thanks

    ok, what if we went for

    take each word,
    explode it,
    if first character is a letter then this is a word
      carry on filtering if you find a space then go to next group
        if you find a number before you find a space treat as bad_word
    if first character is a number then this is a number group
      carry on filtering if you find a space then go to next  group
        if you find a letter before you find a space treat as bad_word

    ok, your stuffed if you're telling the world about your love of U2, otherwise you should be ok... what do you think?

    Better rude word filter... when they change le++er5 for characters

    in PHP Coding Help

    Posted

    I am using a simple but effective “bad word” filter on my site –

    Bad_word Filter code:

    Code:

    [code]
    $bad_words = explode('|', 'badword1|badword2|badword3|etc|etc');
      foreach ($bad_words as $naughty)
      {
          $comments = eregi_replace($naughty, "#!@%*#", $comments);
      }
    [/code]

    but as always when you solve one little problem you come up with another, those pesky kids and their rude #!@%*# words.

    As I’ve added words to the filter they are replaced with other words where one or more characters have been replace with symbols or digits. i.e. in the word ‘*****’, [sorry for any offence to Meredith Brooks fans, or anybody else for that matter] this is easily be filtered on its own using a list, but the same word spelt w1tch, wi+ch etc. could be equally offensive.

    Any ideas? (Short of trying to work out every connotation of every word)

    Help with someone else's RSS feed Script PLEASE!!!

    in Third Party Scripts

    Posted

    [already posted in third party scripts]
    I hope someone out there may be able to help me out here. I have been trying to pull a few feeds into my page from Blogger and a couple of other sources with mixed success. I have to date been using Aaron Dunlaps script RSS_Get [http://www.aarondunlap.com/?content=rss_get] and if you look to the bottom right of my page [http://mouse.nodstrum.com/blog_links.php] you’ll see that under the heading of ‘The After the Mouse blog’ the feed from Aaron’s blog comes through just fine but all the others are, well useless! And that’s because they’re Atom feeds from Blogger…

    I will admit I know zip about the workings of XML weather its Atom or RSS so can anyone tell me where I need to make alterations to the code to make it Atom friendly

    RSS_Get code
    [code]

    <?php

      #==========================
      # The following line declares how long to wait before reloading the RSS feed.
      # Keep in mind, many sites discourage people from pulling its feed more often than 30 minutes.
      # For example, Slashdot.org may ban your server if it tries to load the rss feed too often.
     
      # You may change the below line.
      #==========================

      $minutes = 30; //How often to update the image. 0 indicates that image updates every time it is called (heavy strain on bandwidth & server)

      #==========================
      # The next line is what directory to dump the htm files generated by this script.
      # It should be relative to the location of this script, and it *MUST* have a trailing slash if it's a seperate dir.
      # If you want the files to be dumped in the same dir as this script, set it to ""

      # You may change the next line
      #==========================
     
      $filename = "rss/";
     
      #==========================
      # The next 4 lines are default settings for the script to use, if they are not set prior to including this script
      # You may change the next 4 lines.

      $default_number = 5; //How many headlines to display. If you set it higher than the ammount of headlines, it will stop there
      $default_target = "_self"; //Target for headline links. Options: "_self" and "_blank"

      #==========================
      # The next line is whether or not the script should auto-update.
      # If enabled, the script will check to see if a newer version of this script is available and will
      # automatically download and install it. Your current version of the script will be backed up  in your $filename
      # directory.

      # If you have manually edited this script, you should disable this. Otherwise, it is recomended that you enable it.
      # Also note, your customized settings (default_url, default_displayname, filename, etc) WILL be kept during
      # auto-updates. Alterations to the actual function code (beneath) would be overwritten in an update.

      # During updates, your existing script is backed up into the $filename directory as "backup_[date]_(time).php"

      #                the default is FALSE, which wont truncate
      #                at all.
     
      #                You may use $trunc when calling this script
      #                to define the truncation for specific feeds

      #                for example, if your headlines contain useless
      #                data at the end, like "(via Reuters)", setting
      #                the delimiter to "(" will stop that from showing.
     
      #                You may use $delim when calling this script

    On This day in History… Array issues

    Many thanks

    [code]
    <?php

    // Array Structure:  "Date","Quote","Year"

    $allqts = array
        (
    "1410", "tim created script...", "2006",
    "1510", "tim posts script on site...", "2006",
    "1610", "tim has minimal success...", "2006",
            );

    // Gets the Total number of Items in the array then Divides by 3 because there is a date then a Quote followed by a year
    $totalqts = (count($allqts)/3);

    // Subtracted 1 from the total because '0' is not accounted for otherwise
    $nmbr =($totalqts-1);
    $nmbr = $nmbr*3;

    // I think this is where it's going wrong...
    $quote = $allqts[$nmbr];
            $nmbr = $nmbr+1;
    $year = $allqts[$nmbr];
    $nmbr = $nmbr+2;

    RSS and Atom headline feeds to a page

    in Third Party Scripts

    Posted

    I hope someone out there may be able to help me out here. I have been trying to pull a few feeds into my page from Blogger and a couple of other sources with mixed success. I have to date been using Aaron Dunlaps script RSS_Get [http://www.aarondunlap.com/?content=rss_get] and if you look to the bottom right of my page [http://mouse.nodstrum.com/blog_links.php] you’ll see that under the heading of ‘The After the Mouse blog’ the feed from Aaron’s blog comes through just fine but all the others are, well useless! And that’s because they’re Atom feeds from Blogger…

    I will admit I know zip about the workings of XML weather its Atom or RSS so can anyone tell me where I need to make alterations to the code to make it Atom friendly

    RSS_Get code
    [code]

    <?php

      #==========================
      # The following line declares how long to wait before reloading the RSS feed.
      # Keep in mind, many sites discourage people from pulling its feed more often than 30 minutes.
      # For example, Slashdot.org may ban your server if it tries to load the rss feed too often.
     
      # You may change the below line.
      #==========================

      $minutes = 30; //How often to update the image. 0 indicates that image updates every time it is called (heavy strain on bandwidth & server)

      #==========================
      # The next line is what directory to dump the htm files generated by this script.
      # It should be relative to the location of this script, and it *MUST* have a trailing slash if it's a seperate dir.
      # If you want the files to be dumped in the same dir as this script, set it to ""

      # You may change the next line
      #==========================
     
      $filename = "rss/";
     
      #==========================
      # The next 4 lines are default settings for the script to use, if they are not set prior to including this script
      # You may change the next 4 lines.

      $default_target = "_self"; //Target for headline links. Options: "_self" and "_blank"

      #==========================
      # The next line is whether or not the script should auto-update.
      # If enabled, the script will check to see if a newer version of this script is available and will
      # automatically download and install it. Your current version of the script will be backed up  in your $filename
      # directory.

      # If you have manually edited this script, you should disable this. Otherwise, it is recomended that you enable it.
      # Also note, your customized settings (default_url, default_displayname, filename, etc) WILL be kept during
      # auto-updates. Alterations to the actual function code (beneath) would be overwritten in an update.

      # During updates, your existing script is backed up into the $filename directory as "backup_[date]_(time).php"

      #                at all.
     
      #                You may use $trunc when calling this script
      #                to define the truncation for specific feeds

      #                for example, if your headlines contain useless
      #                data at the end, like "(via Reuters)", setting
      #                the delimiter to "(" will stop that from showing.

    RSS/Atom Feeds TO my site, where to begin?

    in PHP Coding Help

    Posted



    Note to self:- I should explain this better…

    Ok so here goes. I haven seen this done much but I am sure it is out there… I have set up a page on my site where I intend to offer RSS or Atom feeds from several blogs on a similar or complimentary theme to my main site. The page is at http://mouse.nodstrum.com/blog_links.php and I am just wondering how the adding feeds thing works. There must be a trick to it but I am at a loss where to start. I have looked around for a simple tutorial or even a prewritten script but to no avail…

    Can anyone point me in the right direction?

    secure tell a friend....

    in PHP Coding Help

    Posted

    Hi all,

    My php skills are ok, and I thought I’d got things sorted but… my site will be heavily dependant on word of mouth for its proliferation so I used a “tell-a-friend” script. Put it on line and 12 hours later my first spammer hit and I took the script offline!

    So, does anyone have any suggestions, scripts, ideas on how a script can be made more secure?

    To be honest I am now getting bogged down with work on other areas of the site and could use a ready-made script…

    Many thanks
