PHP - Display Files In Array From End To Beginning

Hello all,

I need to make a rotating banner system for a client. They want about 5 banners to rotate with Javascript. However they want the visitor to sort of step through each one on each refresh.

So if I have 5 banners and I go to the site, I see banner 1 and then the javascript rotates through each one.

When I go back to the site, they want it to start with banner 2 and then the javascript will rotate through each one. Then on and on. Go back and see banner 3, then step through again.

I have a nice Javascript image slider I'd like to use. It basically just requires the images in order. Like:

<img src="1.jpg"/>
<img src="2.jpg"/>
<img src="3.jpg"/>
<img src="4.jpg"/>
<img src="5.jpg"/>

I've thought about it and I think the best way to do this would just be using PHP and a cookie. So when the viewer first goes to the site, PHP checks for the cookie. If it exists, it pulls the starting image #. If it doesn't, it starts at 0 and sets the cookie.

As for the images part, I figured an associate array would work well. The key would be what the cookie logic is based on, and then the image HTML would be in the array.

So you visit the site without a cookie it would be...

0 => <img src="1.jpg"/>
1 => <img src="2.jpg"/>
2 => <img src="3.jpg"/>
3 => <img src="4.jpg"/>
4 => <img src="5.jpg"/>

Then when you go back to the site, I need the array to be re-ordered like this:

0 => <img src="2.jpg"/>
1 => <img src="3.jpg"/>
2 => <img src="4.jpg"/>
3 => <img src="5.jpg"/>
4 => <img src="1.jpg"/>

What's the best way to go about this array logic? My experience with manipulating data inside arrays is rather limited. Basically I need it to say "Start with key # and then reorder array based on that"

How would I copy an array of selected files? I know how to list them using a 'for' loop, and how to separate them using a 'foreach' loop, but I am unable to get a checkbox array to copy to a destination folder. Help is appreciated.

Hi, I have this php code to display the url of the files and it works fine, it just has a weird order when it is echoed out.
Here is the code: Code: [Select]
<?php
$date = date("Y-m-d");
$picarray = array();
        $handle = opendir ('pqimages/'.$date.'/');
        while (false !== ($file = readdir($handle))) {
            if($file != "." && $file != "..") {
                $picarray[] = "http://randomaydesigns.com/pqimages/".$date."/".$file."";
            }
        }
$json_array = json_encode($picarray); 
echo $json_array;  
?>There are three files in the folder and they are 33,34,35.jpg it displays them like 33,35,34.jpg

Any Recommendations?
Thanks,
GEORGE

Hello,

I'm making a imagegallery and when someone upload a new image that image has to appear as first picture of the gallery.
I'm using an array for the files, but how can I sort the files on date, newest first.?

<?php
$n = 0;
$pathToThumbs = "images/tekeningen/";
$dir = opendir( $pathToThumbs );
while (false !== ($fname = readdir($dir))){
      
      // strip the . and .. entries out
     if ($fname != '.' && $fname != '..'){
     $tekeningen[$n] = $fname;
    } echo $tekeningen[$n]."<br />"; 
     $n = $n +1;
}
   closedir( $dir );
?>


I found solutions with ksort and filemtime, but I don't understand them and/or they didn't work for me.

Hi,

I'm hoping someone can help me with a simply array problem.

I have a table with two columns: "ID" and "Name" and 100 Names.

I also have an array called $myIDList containing 10 IDs. I want to display 10 Names from the table that correspond with the IDs from my array.

Originally, I tried to implode the array, adding commas and inserted into my MySQL query using:

$myQuery = "SELECT ID, Name FROM namesTable WHERE ID IN ($myImplodedIDList)";

The problem was that duplicated names (i.e. the same Name, but assiged to different IDs) would only be displayed once.

So now I'm trying to use the original array to loop through a second array and display Names where the ID matches an ID from my first array. I have succesffuly listed the table like this:

$myQuery = "SELECT ID, Name FROM myTable ORDER BY ID";

$myResult = mysql_query($myQuery) or die(mysql_error());

    while($row=mysql_fetch_array($myResult)) {
         echo $row['ID'];
         echo $row['Name'];
    }

But I want to do something like:

    while($row=mysql_fetch_array($myResult)) {
      while $row['ID'] = $myIDList {
      echo $row['Name']
      }
    }

Can someone shed some light onto this for me please?

Thank you!

I'm reading through this book which is actually not bad but, on page 286 there's a shopping_cart.php code (which I downloaded from the web site). The code that seems relevant to me is this:


<?php
$totalPrice = 0;
 
foreach ( $_SESSION["cart"] as $product) {
   
  $totalPrice += $product->getPrice(); //<<<LINE 94
?>

The error I get is

Fatal error: Call to a member function getPrice() on a non-object in C:\usr\web\shopping_cart.php on line 94

Should $product be a cast to the Product object?

class Product {
  private $productId;
  private $productName;
  private $price;

  public function __construct( $productId, $productName, $price ) {
    $this->productId = $productId;
    $this->productName = $productName;
    $this->price = $price;
  }

  public function getPrice() {
    return $this->price;
  }
 //etc.

}

The below code returns a radio list after an input box in a profile edit section.
All I want to do is add a space at the beginning of the radio list so to separate the input box and the radio list.
Where the magic happens here is on this line:

return $selhtml . '&nbsp;' . getFieldIcons( $_CB_framework->getUi(), $required, null, $fieldHandler->getFieldDescription( $field, $user, $output, $reason ), $fieldHandler->getFieldTitle( $field, $user, $output, $reason ) );


I've tried several variations of trying to use &nspb; both in the return string directly as well as creating a var for it. I've tried various ways of wrapping it in a div to simply add a margin, I've tried kicking my dog, I've tried banging my head against the wall, nothing seems to work. I either get a t var error, an unexpected something or other like . or & error depending on what I'm doing, or it tries to divide by zero using /'s.

Here's a larger view of the code:

function onFieldIcons( &$fieldHandler, &$field, &$user, $output, $reason, $tag, $type, $value, $additional, $allValues, $displayFieldIcons, $required ) {
global $_CB_framework, $ueConfig, $_CB_fieldIconDisplayed;

if ( is_object( $field->params ) ) {
$privacyLevel = $field->params->get( 'plug_cbprivacy_level' );
} else {
$privacyLevel = 0;
}

if ( $displayFieldIcons && ( $reason != 'search' ) ) {
if ( ( $privacyLevel == 1 ) && ( $field->profile != 0 ) ) {

$privacy =& moscomprofilerPrivacy::getInstance( $user, 'field', $field->fieldid );
$selected = ( $privacy ? $privacy->rule : '' );

$selectorName = $field->name . '___cbprivacy';

$connTypes = array();
if ( $this->params->get( 'conns_by_type', 0 ) ) {
if ( $ueConfig['connection_categories'] ) {
$connTypes = explode( "\n", $ueConfig['connection_categories'] );
foreach ( array_keys( $connTypes ) as $k) {
$connTypes[$k] = trim( $connTypes[$k] );
}
}
if ( $selected == 2 ) {
$type = $privacy->getParam( 'conn_cat' );
if ( $type ) {
$selected = $selected . '|*|' . $type;
}
}
}
$options = array();
$options[] = moscomprofilerHTML::makeOption( '', '' . CBTxt::T('&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;') );
if ( ( $ueConfig['allow_profileviewbyGID'] == -2 ) && $this->params->get( 'prop_registered', 1 ) ) {
$options[] = moscomprofilerHTML::makeOption( '1', '' . CBTxt::T('&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;' ) );
}
if ( $ueConfig['allowConnections'] ) {
$prop_connections = $this->params->get( 'prop_connections', 1 );
if ( $prop_connections ) {
$options[] = moscomprofilerHTML::makeOption( '2', '' . CBTxt::T( '&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;' ) );
}
if ( count( $connTypes ) > 1 ) {
foreach ($connTypes as $type ) {
$options[] = moscomprofilerHTML::makeOption( '2|*|' . htmlspecialchars( $type ), ( $prop_connections ? '&nbsp;&nbsp;&lfloor;&nbsp;' : '' ) . '' . sprintf( CBTxt::T( 'Only for %s' ), $type ) );
}
}
if ( $this->params->get( 'prop_fofs', 1 ) ) {
$options[] = moscomprofilerHTML::makeOption( '3', '' . CBTxt::T( 'Also for friends of friends' ) );
}
}
if ( $this->params->get( 'prop_invisible', 1 ) ) {
$options[] = moscomprofilerHTML::makeOption( '99', '' . CBTxt::T( '&nbsp;' ) );
}
$selHtml = moscomprofilerHTML::radioList( $options, $selectorName, '', 'value', 'text', $selected, 2, false );
if ( isset( $_CB_fieldIconDisplayed[$field->fieldid] ) ) {
return $selHtml;
} else {
$_CB_fieldIconDisplayed[$field->fieldid] = true;
return $selHtml . '&nbsp;' . getFieldIcons( $_CB_framework->getUi(), $required, null, $fieldHandler->getFieldDescription( $field, $user, $output, $reason ), $fieldHandler->getFieldTitle( $field, $user, $output, $reason ) );
}
} else {
if ( isset( $_CB_fieldIconDisplayed[$field->fieldid] ) ) {
return null;
} else {
$_CB_fieldIconDisplayed[$field->fieldid] = true;
return getFieldIcons( $_CB_framework->getUi(), $required, $field->profile, $fieldHandler->getFieldDescription( $field, $user, $output, $reason ), $fieldHandler->getFieldTitle( $field, $user, $output, $reason ) );
}

}

} else {
return null;
} 
}


The basic layout here is this:
|inputbox||radio list|
But I want:
|inputbox|  |radio list|

$i = 0;
while($i < 10) {

   if ($i == 7) {
     //Do Function
   } else {
     $i++
    Go back to beginning of loop
  }

  //More if statements here.
}

Hi,

I have two variables: $latest_note and $notes. Whenever I update $latest_note, I also want this (and today's date) to be added to $notes, such that $notes becomes a sort of archive of all of the latest notes, listed by date.

I tried creating a third variable called $full_notes and saying
$full_notes = $latest_note.$notes; ... then when I run my mysql update, I set notes='$full_notes' but it's not working properly.

Is there a way to simply add one variable to the beginning of another in the db directly, concatenating the two?

Thanks!

My first post.    I am trying to import images related to a particular listing ID.  Currently, I have to enter the number of available photos into a db table, and run the following loop;   <section id="photos">   <?php $b = $row['PIX'];
for ( $a = 01;  $a <= $b;  $a++ ) {
echo "<a href=\"../imgs/{ $row[ 'ID' ] }-" . { $a } . ".jpg\" ><img src=\"../imgs/{ $row[ 'ID' ] }-" . { $a } . "_tn.jpg\"  /></a> " ; } ?> </section>   I would like to find a way to import all the images that begin with the $row[ 'ID' ], but without me having to enter/store { $b } (the number of images recorded in the db).   How can I accomplish this?     _

I keep getting errors that are associated with one-off and one-time occurrences.

I want to tell the script to just restart itself from the beginning if it encounters any type of error, whether it by a fatal error, or any other kind.

is there a way to do this?

Hello guys, im using this code atm and it's working, but the new rows created are put in the end of the table. I want them to stack up from the beginning pushing older rows down. What should i do to make that work?


<?php
$con = mysql_connect("localhost","*****","*******");
if (!$con)
  {
  die('Could not connect: ' . mysql_error());
  }

mysql_select_db("ananaz_se", $con);

$sql="INSERT INTO stuff (adult, namn, url)
VALUES
('$_POST[adult]','$_POST[namn]','$_POST[url]')";

if (!mysql_query($sql,$con))
  {
  die('Error: ' . mysql_error());
  }
echo "1 row added";

mysql_close($con)
?>

Hi,

I've always used PHP code in my websites in a procedural manner as I come from a html/css background. Now that I want to do projects with more complexity I'm thinking I need to approach development in a more Object Oriented fashion.

My question is more a theoretical one. I'm creating a User class and I'm not sure on what is the best practise for putting my functions etc. and where to call them.

My project will have 2 different users (Admin & End User) so is it correct to say that the User class should encapsulate all the functions of both of these users ? By that I mean create/delete/modify user, login & change password/forgotten password functionality rather than having a seperate Login class

Should I only call the database functions within these methods of the user class as opposed to calling them on the php page where the form data is posted ?

For example, if a user logins in and when the form data is posted I currently open a connection, validate data, run the query.
In an OO approach would I have just one User class method thats relevant to a particular page functionality ?
Say, in pseudo code, for handling a login request

loginRequest.php
Code: [Select]
include User class

try {
create new user User();
User::login();
}
catch Exception()



and should my User class look something like this

class.User.php
Code: [Select]
include DBase class

class User {
 var name,
 var email,
 var password,

function validateInput (email, password) {
     if (!valid input)
         throw Exception
    else
       return true
}

function login (email, password){
    try {
       database connection
       validateInput();
       sql to see if user exists and login
       
   }
   catch Exception
}

}

Apologies for this being a bit long winded!

thanks

Hello, I have this XML file I am parsing and I have hit a small formatting issue that I can't seem to get around.    Here is what the the output of the RSS looks like. 

<description><![CDATA[<div style='text-align:left;'>Exit ramp closed. <br/><b>Current Status:</b> Open<br/><b>Affected Lanes:</b> Exit Ramp<br/><b>Dates:</b> Wednesday, May 28 - Thursday, May 29<br/><b>Days Closed:</b> <font color='#808080'>S</font><font color='#808080'>M</font><font color='#808080'>T</font><font color='#FF0000'><b>W</b></font><font color='#FF0000'><b>T</b></font><font color='#808080'>F</font><font color='#808080'>S</font>&nbsp;&nbsp;&nbsp;20:00 PM - 6:00 AM</div>]]></description>

Notice at the first is "Exit ramp closed." There is nothing before it but, for some weird reason when I parse it. It is on a new line like so, notice it should be up there with "Incident" but, it is dropped down below it. 

Incident:
Exit ramp closed. 
Current Status: Open
Affected Lanes: Exit Ramp
Dates: Wednesday, May 28 - Thursday, May 29
Days Closed: SMTWTFS   20:00 PM - 6:00 AM

This is how it is formated in the td cell. 

<td style='{$td2Style}'><strong>Incident:</strong> {$incident_data_desc}</td>\n";

So as you can see above, there is nothing before it that would cause it to break to a new line both in the table or in the RSS.    So how can I remove that first return only is that is on the same line with it and not below it.    I have tried this and a couple of other things like trim with no luck.   

$description         = $item->description;
    $incident_data_desc  = str_replace("\r", '', $description );

Note, I only need that first one removed, the others are fine. I can do it but it will remove all the breaks and I only want to remove that first one that is causing the line to be on a new line.    Any suggestions?   -Thanks

Hi,

Is it possible to display the whole array of voteID in this url?

https://falling-skies-tv.loopiasecure.com/vote_result.php?voteID=292&comp=falling-skies-danmark

Is there a script/website/code I can use?

Thank you!
