Similar Tutorialshi, i am having issues with sorting within a conditional statement. please see the code below. right now, i ve commented out the sorting below. basically i want to sort by: $venue1->hereNow->count. I am managing to pull the data correctly. see: http://marineboudeau.com/lab/4sq/ <?php if (is_object($venue->response)) { //sort($venue->response->groups[0]->items->hereNow->count); foreach ($venue->response->groups[0]->items as $venue1) { if ($venue1->hereNow->count != '0'){ //var_dump ($venue1); echo "<div style='font-weight:bold;'>".$venue1->name."</div>"; echo "<div>".$venue1->location->address." ".$venue1->location->city."</div>"; echo "<div>".$venue1->hereNow->count."</div>"; echo "</br>"; } } }?>() any idea what i need to do to make it happen? thank you. marine I wonder whether someone can help me please. I've put together the script below, which allows users to view their saved images in the original folder structure that they were saved in. Code: [Select] <?php session_start(); $_SESSION['username']=$_POST['username']; $_SESSION['locationid']=$_POST['locationid']; ?> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <?php $galleryPath = 'UploadedFiles/' . $_SESSION['username'] .

'files.xml') and line 54 is: Quote foreach ($items as $key => $value) { I know that in their own right, the piece of code which loads 'files.xml' and the code which loads the folders and images work, but it's combining them that creates the issue. I've done some research online, and I think the issue is to do with 'Session' variables and the 'foreach' array, but I'm not sure how to solve the problem. I just wondered whether someone could perhaps have a look at this please and let me know where I'm going wrong. Many thanks and regards Alright the issue that I am having is that I need to get multiple lines into a variable to output later in the code. my $pieces variable is not returning anything, much less missing parts of it, but even the text code is not returning.
foreach($packages as $pack)
{
$weight+=$pack->weight;
$items_no++;
$singleweight=$pack->weight;
$length=$pack->length;
$height=$pack->height;
$width=$pack->width;
$pieces .= '<piece actual_weight="'.$singleweight.'" length="'.$length.'" height="'.$height.'" width="'.$width.'">';
}
if(!empty($post_code) && $weight>0 && $items_no>0)
{
$data='?shipment='.urlencode('<shipment weight_system="IMPERIAL" shipper_number="'.$this->shipper_number.'" destination_postal_code="'.$post_code.'" service_type="'.$service.'">'.$pieces.'</shipment>').'&token='.$this->token;
// $woocommerce->add_message('Items No:'.$items_no.'- Postalcode:'.$post_code.'- ');
$resp=file_get_contents($this->canpar_url.$data,false,$context);
If I do this in another method that only requires a single line (getting the total weight and number of items) it works fine, but this does not return the proper shipping cost for low weight items. On a site where higher weight items is shipped the plugin works fine. However I need to modify it to work based on dimensions. The result I am looking for is something like this:
https://www.canpar.com/XML/RatingXML.jsp?shipment= <shipment weight_system="IMPERIAL" shipper_number="42500047" destination_postal_code="M1M1M1" service_type="1"> <piece actual_wieght="7" length="24" height="24" width="24"/> <piece actual_wieght="5" length="10" height="12" width="14"/> </shipment> &token=WZHBRS4KQYNAusing an output system I can output weight, packs, length, width, height but it does not return anything for $pieces and obviously shipping costs because I am getting an invalid xml response.
$woocommerce->add_message('Weight: '.$weight.' Packs: '.$items_no.' Shipping cost : '.$atts['total_charge'].' Pieces: '.$item_box.' Length: '.$length.' Width: '.$width.' Height: '.$height);
This is more of a technical question that i could not find the answer to pn the php.net manual pages. take the folowing example code: foreach ($array as $key => $value){ $tempvariable = some_property_of($value); } unset($tempvariable); is that unset statement needed? Does PHP automatically destroy the variables once the foreach loop is left? Hello, i have the code below and i need to have all results in a variable as a string, inside the loop they are displayed how i want but outside will echo the last result. Thank You. Code: [Select] foreach($_POST as $key=>$value){ if (is_numeric($value)) { $valoare = "$value,"; } } echo $valoare; hey guys, I'm quite new to PHP and i was wondering if someone would be able to help me out with this. The code i have checks the database to see if a user has provided a Vimeo ID. If they haven't, $video_check will equal a line of html that says the user hasn't added any videos to their portfolio. If the a vimeo ID is present, i want $video_check to equal a bunch of html and css with a foreach function inside that is used to display the users videos from vimeo. The foreach function works fine when its not assigned to the $video_check variable. How do i structure it so that it displays correctly? If you click on videos on this page you might get a better idea of what i'm talking about. http://www.myfilmportfolio.ie/profile.php?id=33 and here is the code i'm having the problem with: /////// check if user has provided vimeo id ////////////////////////// $vimeoID = $row["vimeoID"]; $video_check=''; if (empty($vimeoID)){ $video_check = '<h3>'.$firstname .' has not added any videos to their portfolio</h3>'; } else{ $video_check = '<div id="stats"> <div style="clear: both;"></div> </div> <div id="wrapper"> <div id="embed"></div> <div id="thumbs"> <ul> <?php foreach ($videos->video as $video): ?> <li> <h4><?=$video->title?></h4> <a href="<?php echo $video->url ?>"> <img src="<?php echo $video->thumbnail_medium ?>" class="thumb" /></a> <p><?=$video->description?></p> <br /> </li> <?php endforeach ?> </ul> </div> </div>'; } if anyone could help me out id really appreciate it. Cheers, G Hello. I want to create some variables dynamically. I have this so far: for($i = 1; $i <= 4 ; $i++){ $a = 'member' . $i; $$a = array(); } Does that give me this 4 arrays?: $member1, $member2, $member3 and $member4? Of course I want some process inside of the loop, but that would depend on the variables. Would that work? thanks! Hi All, For the last post,I m very happy that i found out so many great mind who are watching my problem and solving online. anyway great thanks for all, just now i m making a project and i m facing problem in the below code "i need to know how can make this code easy or how can i make rdata variable accessible for the download button" generatecv.php file <?php if(isset($_REQUEST['submit'])) { $name=$_REQUEST['pname']; $pin=$_REQUEST['pin']; $mnumb=$_REQUEST['mnumber']; $tnumb=$_REQUEST['telenumber']; $email=$_REQUEST['email']; $obj=$_REQUEST['obj']; $title=$_REQUEST['jobt']; $activity=$_REQUEST['activity']; //$file=fopen('test.doc','a+'); //echo @fwrite($file,$name); //fclose($file); $rdata=""; $rdata.="<table id='cvtbl' border='0' align='center' > <th>Resume</th> <tr><td>".$name.":</td></tr><tr><td>Objective:</td></tr>"; $rdata.="<tr><td>".$obj."</td></tr>"; $rdata.="<tr><td>Email:".$email."</td></tr>"; $rdata.="</table>"; echo $rdata; echo "<style>#cv{display:none;}</style>"; echo "<form><input type='submit' name='dwnld' id='dwnld' value='Download'/></form>"; } if(isset($_REQUEST['dwnld'])) { header("Content-type:application/msword"); header("Content-disposition:attachment;filename=test.doc"); $fp=fopen("test.doc","r") or die("try again"); $data=fread($fp,filesize('test.doc')); fwrite($fp,$rdata); echo $data; fclose($fp); //echo $rdata."<br />".$rdata; } ?> this is the html file <html> <title>User details</title> <body> <form name='cv' id='cv' method="post" enctype="multipart/form-data" action='generatecv.php'> Enter your name<input type=text name=pname id=pname /> Zip Code<input type=text name=pin id=pin /> Mobile number<input type=text name=mnumber id=mnumber /> <br />Telephone number <input type=text name=telenumber id=telenumber /> Email address<input type=text name=email id=email /> <br />Enter your objective<br /><textarea name=obj id=obj cols=30 rows=5 ></textarea> <!--University Name <input type=text name=university id=university /> --> <br /><!--uni, city ,state ,type of degree ,full degree name,date--> <br /><!--Experience<br /><textarea name=exp id=exp cols=30 rows=5 ></textarea> --> Select type of resume <select name='type' id='type' onChange=''> <option value='0'>Graduate</option> <option value='1'>Post Graduate</option> <option value='2'>Non Graguate</option> <option value='3'>Other</option> </select> Job title<input type='text' name='jobt' id='jobt' /> <br /><!--company name,city ,state ,office number ,job description ,date of employment--> <br />Activity <input type=text name=activity id=activity size=100 /> <br />Honors/Awards<input type=text name=honor id=honor size=100 /> <input type='submit' name='submit' id='submit' value='Generate CV' /> <input type='reset' name='Reset' id='submit' value='Reset' /> </form> </body> </html> Many thanks in advance Hi Guys Ever had the feeling your being a spoon and can't see the wood for the trees? Well, that's how I feel today. All I am trying to to is implement a variable in a "foreach" loop that increments by one through each iteration of the loop. I know how to do it in a "for" loop but can't for the life of me get it to work here. Here is the code: foreach ($cart as $prodcode => $qty) { $item = get_product_details($prodcode); echo '<input type="hidden" name="item_name_'.[b]$needavariablehere[/b].'" value="'.$item['description'].$_SESSION['finish'][$prodcode].$_SESSION['handles'][$prodcode].'" />' . "\n"; } Where I have highlighted $needavariablehere is where I want a number to appear i.e. if there is one item available and the foreach loop iterates once I want the number 1 here. If there are two items and the foreach loop iterates twice I want the output to have number 1 in the first line and number 2 the second time around and so on. How many times the foreach loop iterates is based on the $cart array which contains items in a shopping cart. Thanks for any help you can give guys. I'm creating a website where writers can share stories. I have a section where the users enter a summary of there story. Anyways in the area where the story in being listed I want the the title of the story(with a link to the story) underneath the link I would like a summary. BUUUUT, the summary can get pretty long(up to 900 chars). So I am wondering if I can shorten the variable where the summary is stored, I want it to be shorten to a fixed amount of characters(maybe 200?) then followed by a ... . So how can I do this? When login in (in login.php), the script is assigning user information to scalar variables like so: $user_name = $assoc['user_name']; $user_id = $assoc['user_id']; Now I'd like to make use of those variables on other pages like this for example: echo "Posted by " . $user_name; I want that to be visible for everybody, even if the user logs out. Any ideas? Hello, I'm working on a script which should read lines from a file keyword.txt create a new file with that variable name, insert the content close and loop through all the lines in the keyword file. The loop itself works but now that i'm adding the fopen fwrite and fclose i'm running into trouble. I'm not that great a coder and have pieced this together so far. I'd appreciate any suggestions on how to fix the fopen and other file functions to create unique files using the keywords from the file Thanks in advance <?php $read_file = file('keywords.txt'); foreach($read_file as $var) { $file = fopen($var, "x"); $content = "<!DOCTYPE html PUBLIC \"-//W3C//DTD XHTML 1.0 Transitional//EN\" \"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd\"> <html xmlns=\"http://www.w3.org/1999/xhtml\"> <head> <meta http-equiv=\"Content-Type\" content=\"text/html; charset=utf-8\" /> <title>This is the title</title> </head> <body> <h2>The keyword is $var</h2> <p><p> </body> </html>"; fwrite($file, $content); fclose($file); } ?> This topic has been moved to Application Frameworks. http://www.phpfreaks.com/forums/index.php?topic=355772.0 Well I usually run my scripts in CLI.. I have it do something then sleep for x amounr of settings, is there anyway to make it show me the seconds counting down instead of just a blinkin cursor? I bought script for live chat support but i want something more. Now you can login with admin role and operator role, but what i want is to add user role so when user login in app he can see online operators and chat with them. It is open source so there is no legal issue..
So if anyone wants to help me i will send script on your email and try to solve this..
Thanks,Ivan
im am creating a live search using the w3schools tutorial. apart from im using mysql. here is my current code(which works fine): <?php mysql_connect("localhost", "root", ""); mysql_select_db("dictionary"); $words = mysql_query("SELECT * FROM words"); $a = array(); while ($row = mysql_fetch_assoc($words)) { $a[] = $row['word']; } $q = $_GET['q']; if (strlen($q) > 0) { $hint=""; for($i=0; $i<count($a); $i++) { if (strtolower($q)==strtolower(substr($a[$i],0,strlen($q)))) { if ($hint=="") { $hint=$a[$i]; } else { $hint = $hint . "</b><br /><br /> ".$a[$i]; } } } } // Set output to "no suggestion" if no hint were found // or to the correct values if ($hint == "") { $response="no suggestion"; } else { $response=$hint; } //output the response echo $response; ?> as you can see it is edited alot. But my problem is that i need to display underneath the word, the definition aswell. I've been trying to figure this out but i can't seem to do it. I have been trying to use multidimensional arrays. I'm trying to get live search set up for one of my pages and have been successful for the most part. I basically used the code provided by w3schools (http://www.w3schools.com/php/php_ajax_livesearch.asp) but need to make a modification. Their code is set up to read the link titles and urls from an xml file and search through the xml file but I would like to just search through a variable. So in the w3schools code there is this... $xmlDoc=new DOMDocument(); $xmlDoc->load("links.xml"); $x=$xmlDoc->getElementsByTagName('link'); And I have this variable that I want it to search instead of "links.xml"... $searchTest = "<pages><link><title>Search this text</title><url>www.gohere.com</url></link></pages>"; How do I get that into the $xmlDoc variable? If I simply replace "links.xml" with $searchTest like this $xmlDoc=new DOMDocument(); $xmlDoc->load($searchTest); $x=$xmlDoc->getElementsByTagName('link'); I get nothing when I try to search. But if I create a file in the php code and write the contents of $searchTest to that file then put that file in the $xmlDoc->load("newfile.xml"); line it searches and works fine. Any ideas? Hello sir, I request an help for the live search.. Here are the 2 pages Code: [Select] <html> <form action='?p=search'> <font face='sans-serif' size='5'> <center> Search By the CID.<br> <input type='text' size='50' name='search'> <input type='submit' name'submit' value='Search'> </center> </font> </html> Code: [Select] <?php //get data $button = $_GET['submit']; $search = $_GET['search']; if (!$button) echo "You Have to insert a Valid CID."; else [ if (strlen($search)<=2) echo "Search term too short.The CID contain 6 number"; else [ echo"You searcher for <b>&search</b><hr size='1'>" } } ?> Now i want the live search by the name of the profile... Can someone help me? Hi there I'm a little bit of a newbie when it comes to PHP, and I have tried to find my answer on google and on other websites related to php development.
My question is what do I need to be researching / learning to automatically update a page with content.
For example, if I have a database field called breaking news and this text string is flashed at the bottom of the screen on a scrolling bar.
When the field changes value in MYSQL, I would like the page to automatically update the page without a need for a page refresh.
All I need is some advice on what I need to search for in order for me to learn the coding myself.
I'm thinking AJAX, but not too sure.
Thank you for reading.
Hi everyone,
I'm hoping the someone can guide me in the right direction for what I need to do. Does anyone know of a really good tutorial and/or information about a plugin product that is available to do what I need? For example, what I need is to create a website that has the ability to allow video conferencing between a teacher and students. This what I envision - a college professor can log on to his website and display a live video feed of him. Also, as each of his students log on, their live video feed is then also supplied. Would prefer a already made plugin product but would also like to look at raw code in PHP to see how something like this could be accomplished. Thank you in advance.
Charles
