PHP - Project Approach Question
Hi Guys,
Greetings! Co - PHP freaks! I was hired by a company that requires me to create a purchase department program that will generate Quotations, P.O. , Receipt All of the database of this program will be stored to a server computer in a single office and all of the computer has a software that will access the data and should be able to generate a printable file like PDF or something. What is the best approach for this? any suggestions? I appreciate it in advance.
Cheers,
MrGhaia Similar TutorialsI am wanting to make a product list page with PHP. At the moment I using this code: Code: [Select] $query = "select * from products where category = 'Belts'"; $result = mysql_query($query); while($row=mysql_fetch_assoc($result)) { echo $row['name']; } The result is something like this: http://i51.tinypic.com/2w56ljq.png What I want is for them to be aligned like this: http://i53.tinypic.com/w811tz.png Eventually, I am also going to include an image with each product. How would I go about alignment? With CSS or PHP? Hi everyone,
So I'm relatively new to OO PHP and moreover, OO PHP with MVC design pattern.
This may be a largeish post so please bear with me on this one!
So here is a scenario that I'd like to understand. There are likely multiple ways to go about this, but it'd be nice to see what is said.
I'll include what I think should be the solution here and hopefully i'll get some feedback about it.
Scenario:
A page needs to display a list of "parts" for a car. A database table already exists with these parts. The list of parts on the page need to be ordered by name on first load, but then can be re-ordered by users using a drop down list. They can also be filtered, and searched.
A page also exists to display a single car part.
What I think should be, and what i'm struggling with:
Model:
I will have a "part" object which represents an individual car part.
The part object will use a database abstraction layer. On "new Part()" will generate an empty object. ->Load( id ) will load an individual part.
Controller:
I do not know how I would implement this. I know it would contain methods to Filter(), Search() and Order() and that would directly access the Model.
View:
I am lost here too, I need to display a list of car parts, and on another page, a single car part. I understand I should use the same Model for both. However I do not see how I would list the parts.
Some Questions:
Should I have another "model" that is a list of the "Part" model called PaetListModel, or should "Part" be able to generate that list?
I clearly should have 2 views, one for singular part, one for list of parts. Should the view access the model to generate the list before using the data for output?
Should the controller be used in the view instead of the model to generate the initial list (or singular) on page load?
Should the filter functions in the controller reload the "PartsList" from wherever our list is stored?
I think the most important question for me though is:
How would YOU implement the above green scenario?
I would like to learn from peoples examples so I get an idea of what road to follow
I'm looking for some direction as I approach a new challenge. I have a table named friends_and_family and it contains name, email, and age fields. I'm planning a party and want to invite 10 of the people that are between 20 and 35 years old. The format I am considering would query the table and provide a list of those members that fit the age requirement. I would like to generate that result (which I should be capable of handling) so that each person listed has a checkbox next to their name. I imagine I will be creating a resultant form, so that I can then evaluate the result and select the checkboxes for those specific people that I want to invite. Upon submission, an email will be sent to the people with selected checkboxes. How should I approach this best? A for each loop? Implode an array? I'm not very good with AJAX, so I'm thinking along these lines.
Hello everyone, I am new to php and I need a confirmation if this is the correct approach for a code I wrote. Basically, I have a contacts.php page where I have a bootstrap table and a modal with some fields to add a new contact. I managed to write all the code, it works perfect but I want to know if this approach is ok. The application will be much more complex and I don;t want to start on the wrong foot here. I have 2 files: contacts.php and add_new_contact.php. First file, contacts.php:
<!DOCTYPE html>
<html lang="en" dir="ltr">
<head>
<!-- ............ -->
</head>
<body>
<!-- ............ here is the page layout-->
<!-- Then I have my modal from bootstrap -->
<div class="modal fade" id="addContact" tabindex="-1" role="dialog" aria-labelledby="myModalLabel">
<form action = "add_new_contact.php" method="post">
<!-- .....content with all the inputs -->
<button type="submit" class="btn btn-primary">Save to database</button>
</form>
</div>
</body>
</html>
Now, in form action I am telling html to go to add_new_contact.php where I wrote the code for inserting all the values to the database. When doing this, it opens the page and it stays blank because there is no html there. So, in that php file I added a redirect code to the initial contacts.php. Here is the code: Second file: add_new_contact.php:
<?php
//all the code needed to insert the contact in the database
header("Location: http//..../contacts.php");
exit();
?>
So, this works fine. But is this the best way to do it? Thank you. I currently use HTML strings within my PHP code to display output. And while it might not be best practice, I find it non-restrictive and I can easily add loops, manipulate variables, etc. within my display. However in the interest of having a cleaner code I'm thinking of separating the HTML, without having to use a Template engine like Smarty. I don't care much about replacement patterns to be honest, I don't mind some PHP code withing the HTML, however my biggest issue is loops and having to modify a variable within each loop. Say I have the following example code (Similar to what I'm using right now): Code: [Select] function student_output() { //Retrieve students from array $students_arr = students_info(); $selected_student = $_GET['selected_student']; $output = '<div id="students_container">'; $output .= '<div class="items_list">'; $i = 1; //Loop through students foreach($students_arr as $key=>$value) { if ($selected_student == $key) { $output .= '<div id="student_name_'.$i.'" class="selected">'.$value['student_name'].'</div>'; $output .= '<div id="student_img_'.$i.'" class="selected"><img src="'.$value['student_image'].'" /></div>'; } else { $output .= '<div id="student_name_'.$i.'">'.$value['student_name'].'</div>'; } $i++; } return $output; } What's the best way to represent this in HTML cleanly without having too much PHP code within? So, I'm starting a new project and thought I would try a new approach at loading files and classes to process output. I think my logic is correct, but for some reason I'm getting a blank page. Basically instead of having seperate pages to output different functions and such, I store everything in one page. It's the same deal as the switch case approach, but it uses a foreach loop to cycle through the actions, classes, and functions which are stored in an array. Here's my index.php file: Code: [Select] <?php require('config.php'); include('languages/english.php'); include('classes/Template.php'); $template = new Template; $viewPages = array( 'category' => array('classfile' => 'Category.php', 'classname' => 'category', 'functions' => array('create', 'delete', 'modify', 'merge')), 'questions' => array('classfile' => 'Question.php', 'classname' => 'Question', 'functions' => array('create', 'delete', 'modify', 'votegood', 'votebad')) ); $currentPage = $_REQUEST['action']; foreach($viewPages as $action => $settings){ if($currentPage == $action){ require(INCLUDE_ROOT.'/classes/'.$settings['classfile']); $class = new $settings['classname']; $function = $_REQUEST['do']; $class->$function(); $template->loadTemplate($settings['classname']->viewFile, $vars = array()); if($template->message == FALSE){ die($template->message); } } } ?> Here's the Template class file: Code: [Select] <?php class Template { var $file; var $vars; var $message; function loadTemplate($file, $vars){ if(empty($file) || empty($vars)){ $this->message = LANG_ERR_7; } else if($file = file_get_contents(INCLUDE_ROOT.'/'.$file)){ $this->message = LANG_ERR_7; } else { foreach($vars as $key => $val) $file = str_replace('{'.$key.'}', $val, $file); } $this->message = FALSE; return $file; } } ?> I tried visiting the category action(index.php?action=category;do=create). This is the classfile for that Code: [Select] <?php class category { var $id; var $title; var $description; var $uri; var $message = array(); var $vars = array(); var $viewFile = ''; function create(){ if($_POST['submit']){ //Review the user input and make ure everything is ok $messages = array(); if($this->title == FALSE){ $messages['title'] = LANG_ERR_1; } else if(strlen($this->title) > 30 || strlen($this->title < 5)){ $messages['title'] = LANG_ERR_2; } else if($this->description == FALSE){ $messages['description'] = LANG_ERR_3; } else if(strlen($this->description) > 400 || strlen($this->description) < 10){ $messages['description'] = LANG_ERR_4; } else { $messages = FALSE; } if($messages != FALSE){ $this->messages = $messages; $this->viewFile = INCLUDE_ROOT.'/template/index_body.tpl'; } else { $this->title = htmlentities($this->title); $this->title = stripslashes($this->title); $this->title = htmlspecialchars($this->title); $this->description = htmlentities($this->description); $this->description = htmlspecialchars($this->description); $this->description = nl2br($this->description); $query = " INSERT INTO categories (c_title, c_desc) VALUES('".$this->title."', '".$this->desscription."')"; if(mysql_query($query)){ $this->message['succes'] = LANG_ERR_5; } else { $this->message['fail'] = LANG_ERR_6; } $this->viewFile = INCLUDE_ROOT.'/template/message_body.tpl'; } } else { $this->viewFile = INCLUDE_ROOT.'/template/create_category.tpl'; } } } ?> Now if you look at the Category class, the template file it sets is the "category_create.tpl" file, which I haven't created yet. I'm expecting there to be an error associated with the template class and the file_get_contents function that calls the file, but like I said, I'm just getting a blank page. I've never tried this approach before, so I have no idea what's causing this. Any help would be greatly appreciated. I'm trying to process MS words doc in PHP. I found some samples which use COM applications for this but not working properly (I get only exceptions and no result) and I taught it's the version of word on my localhost or my OS so I tried them on with different windows OS and MS word. but same result, since it would be harder to make it work on remote server (the remote server needs to have MS word installed on) so I'm looking for different approach, what you think?? is there nay good one rather than COM applications? have you ever tried? is it possible to write code with other like ASP or java and combine it with PHP? every little piece of advice would be appropriated, thanks I have good knowledge of HTML, Css, Php and mysql, i would want to know, the best approach to creating an online dating site. any help hello dear community, i am currently wroking on a approach to parse some sites that contain datas on Foundations in Switzerland with some details like goals, contact-E-Mail and the like,,, See http://www.foundationfinder.ch/ which has a dataset of 790 foundations. All the data are free to use - with no limitations copyrights on it. I have tried it with PHP Simple HTML DOM Parser - but , i have seen that it is difficult to get all necessary data -that is needed to get it up and running. Who is wanting to jump in and help in creating this scraper/parser. I love to hear from you. Please help me - to get up to speed with this approach? regards Dilbertone All good with sending single dimensional form data to the server using application/x-www-form-urlencoded, and having PHP convert it into an array. Also, good with sending simple arrays using []. But then I find myself needing to send a deeper object to the server . For example, I have a form with three text inputs simpleFormName 1, 2, and 3 plus some deeper object.
Array
(
[simpleFormName1] => bla
[simpleFormName2] => bla
[simpleFormName3] => bla
[deeperObject] => Array
(
[0] => Array
(
[prop1] => bla
[prop2] => true
[data] => Array
(
[0] => Array
(
[p1] => 321
[p2] => 123
)
[1] => Array
(
[p1] => 121
[p2] => 423
)
[2] => Array
(
[p1] => 221
[p2] => 133
)
)
)
[1] => Array
(
[prop1] => blabla
[prop2] => false
[data] => Array
(
[0] => Array
(
[p1] => 222
[p2] => 443
)
[1] => Array
(
[p1] => 321
[p2] => 213
)
[2] => Array
(
[p1] => 111
[p2] => 421
)
)

I see at least four options: Come up with naming structure which "flattens" the data. I have used this approach in the past, but it quickly becomes difficult to manage and I don't want to do so. Not use PHP's POST and and instead use Content-Type: application/json and file_get_contents(php://input) and json_decode the entire request server side. Use PHP's POST and urlencoding but make deeperObject a string using JSON.stringify and json_decode this one field server side. Urlencode the entire object.simpleFormName1=bla&simpleFormName2=bla&simpleFormName3=bla&deeperObject%5B0%5D%5Bprop1%5D=bla&deeperObject%5B0%5D%5Bprop2%5D=true&deeperObject%5B0%5D%5Bdata%5D%5B0%5D%5Bp1%5D=321&deeperObject%5B0%5D%5Bdata%5D%5B0%5D%5Bp2%5D=123&deeperObject%5B0%5D%5Bdata%5D%5B1%5D%5Bp1%5D=121&deeperObject%5B0%5D%5Bdata%5D%5B1%5D%5Bp2%5D=423&deeperObject%5B0%5D%5Bdata%5D%5B2%5D%5Bp1%5D=221&deeperObject%5B0%5D%5Bdata%5D%5B2%5D%5Bp2%5D=133&deeperObject%5B1%5D%5Bprop1%5D=blabla&deeperObject%5B1%5D%5Bprop2%5D=false&deeperObject%5B1%5D%5Bdata%5D%5B0%5D%5Bp1%5D=222&deeperObject%5B1%5D%5Bdata%5D%5B0%5D%5Bp2%5D=443&deeperObject%5B1%5D%5Bdata%5D%5B1%5D%5Bp1%5D=321&deeperObject%5B1%5D%5Bdata%5D%5B1%5D%5Bp2%5D=213&deeperObject%5B1%5D%5Bdata%5D%5B2%5D%5Bp1%5D=111&deeperObject%5B1%5D%5Bdata%5D%5B2%5D%5Bp2%5D=421 Any recommendations how to best implement? If you recommend using urlencoding for simple forms, but some other approach for more complex data, what criteria do you use to transition from one approach to another? Thanks I am trying to wrap my head around the best approach to accomplish this.
I am trying to come up with a random schedule for a full 24 hour day with random time periods ranges including breaks.
The only constants will be the minimum time and maximum time of the events and the minimum and maximum time of the breaks between each event.
for example
There are three teams
Team A
Team B
Team C
Each event will last either a minimum of 7 minutes to a maximum of 38 minutes
The breaks will last a minimum of 30 seconds to a maximum of 5 minutes.
so the events need to be generated randomly with a break period following each event and the timelines are different for each team
with the current event time left going to a timer on the page
I think I have the part to generate the random blocks figured out by using
<!DOCTYPE html>
<html>
<body>
<?php
function eventRange($min, $max, $blocks) {
$events = range($min, $max);
shuffle($events);
return array_slice($events, 0, $blocks);
}
function breakRange($min, $max, $blocks) {
$breaks = range($min, $max, 0.1);
shuffle($breaks);
return array_slice($breaks, 0, $blocks);
}
echo"<pre>";
print_r( eventRange(7,38,32) );
echo"</pre>";
echo"<pre>";
print_r( breakRange(.5,5,32) );
echo"</pre>";
?>
</body>
</html>
bur is there a way to make it fill a full 24 hour period and then a way to determine which block to display based on the current time when either team is viewing the page.
Sounds totally confusing to me as I try to explain it so I hope what Im asking makes sense. Thanks for any guidance..
good evening dear Community, Well first of all: felize Navidad - I wanna wish you a Merry Christmas!! Today i'm trying to debug a little DOMDocument object in PHP. Ideally it'd be nice if I could get DOMDocument to output in a array-like format, to store the data in a database! My example: head over to the url - see the example: the target http://dms-schule.bildung.hessen.de/suchen/suche_schul_db.html?show_school=8880 I investigated the Sourcecode: I want to filter out the data that that is in the following class <div class="floatbox"> See the sourcecode: <span class="grey"> <span style="font-size:x-small;">></span></span> <a class="navLink" href="http://dms-schule.bildung.hessen.de/suchen/index.html" title="Suchformulare zum hessischen schulischen Bildungssystem">suche</a> </div> </div> <!-- begin of text --> <h3>Siegfried-Pickert Schule</h3> <div class="floatbox"> See my approach: Here is the solution return the labels and values in a formatted array ready for input to mysql! <?php $dom = new DOMDocument(); @$dom->loadHTMLFile('http://dms-schule.bildung.hessen.de/suchen/suche_schul_db.html?show_school=8880'); $divElement = $dom->getElementById('floatbox'); $innerHTML= ''; $children = $divElement->childNodes; foreach ($children as $child) { $innerHTML = $child->ownerDocument->saveXML( $child ); $doc = new DOMDocument(); $doc->loadHTML($innerHTML); //$divElementNew = $dom->getElementsByTagName('td'); $divElementNew = $dom->getElementsByTagname('td'); /*** the array to return ***/ $out = array(); foreach ($divElementNew as $item) { /*** add node value to the out array ***/ $out[] = $item->nodeValue; } echo '<pre>'; print_r($out); echo '</pre>'; } well Duhh: this outputs lot of garbage. The code spits out a lot of html anyway. What can i do to get a more cleaned up code!? What is wrong with the idea of using this attribute: $dom->getElementById('floatbox'); any idea!? any and all help will greatly appreciated. season-greetings db1 Hi, I need more than one person on my team for my project, I was wondering if someone will join and help me. My project it a website software (kind of like a CMS). This won't be paid. That's the only problem.
well done really need help but this seemed the best place to put it well i was wondering what would be easy 1st project for a beginner to make in php, About Me Hi, firstly let me introduce myself. My name is Liam O'Connor and I'm 17 years old, 18 soon (quite excited) living in the UK and I've been learning how to makes websites ever since I was 16. Within the last 2 years I have taught myself (x)HTML/CSS, PHP/MySQL, JavaScript/Ajax to a good standard. I'm currently at college doing a Computing Networking and Security Extended Diploma. The Project I have been working on a website for many months now that I REALLY love doing. When ready for launch the website will be a simple social networking website that lets users communicate in groups or one-on-one, also users will be able to create chats on the topics they like to talk about and personalise them to how they like. What have I done so far? Within the last few months I have created a well working chat system that allows many users to communicate together, and many features within the chat such as emoticons, change status (online, busy, away), control of font size, sound alerts, chat comments, and a thumb rating system. What could you do? If you are interested to help develop a website like this one (for free) in your own time, please contact me and let me know a little about you and what you think you would be able to offer. There is no rush to get this project finished and put live for the world to see so there would be no pressure on you. If you are not interested in developing the website but you believe you have some wise words of wisdom please share them with me or if you believe you can help in any other way please let me know. Please check out the image below Thanks Hello I am new to the forums and this is my first post A little about me, I have played around with php time to time but don't know how to code it, I can modify it and use scripts and what not but I can't find a script that I wan't to do this I wan't to be able to upload and file share site without using mysql and using cookies instead to keep track of user's upload's without having them to register a account, I don't want a user management system for this I just want them to be able to upload a file and it keep track of their upload's(I can set a limit of course), and be able to share the direct link to their friends for them to quickly download it. I need to know what steps I need to do and how to start basically and if anyone can help me out. Thank you PHP Freaks So I am working on a project in which I am taking pictures from an SSH area, running ImageMagick on the picture to crop out what I want and then use the threshold to make it like I want, and then finally run Tesseract OCR on the final picture. I have a new picture coming in to the spot I am taking the pictures from every six seconds and I need the program to run the commands to do all of this every six seconds as the pictures come in forever basically. As of right now, here is my code that I have. I am relatively new to using PHP scripting working for the command line in Ubuntu. So if anyone could help me with some fixes to this code, I would be greatly appreciative.

I'm a beginner in php.I know some basic codings in it.I want to do the project in php.Help me how to start..?..and what kind of project is best for beginners to learn..?
Hi all, I am an intermediate PHP Programmer, but I'm now stuck with getting any further. I am currently developing a CMS with a few people. However, I wish to put that aside for a month or so and learn PHP a bit better. Can anyone suggest a fairly "easy" project for me to do to learn a bit more about PHP? Best Regards, DM with my limited PHP programming skills I have managed to successfully a produce a css button maker which makes and produces the code for a number of resolutions and devices. this is the $result displayed Code: [Select] $result = "<a href='#' class='blnk'><li class='btn rnd'>" .$_SESSION['text'] ."</li></a>"; ($_SESSION['result']==$result); this is how each device is called: Code: [Select] #### ANDROID ####### if ($_SESSION['device']=="android") { echo "<div id='andt'></div><div id='andm'><div id='and-st'><div id='btn'>"; $i=1; while($i<=$_SESSION['nbr']){ echo $result; $i++; } echo "<div class='cl'></div></div></div></div><div id='andb'></div>";} This is the dropdown for the bumber of buttons Code: [Select] <legend> Button No</legend> <select name="nbr"><option value="<? echo $_SESSION['nbr'] ?>"><? echo $_SESSION['nbr'] ?></option><?php include('inc/f-1to8.php'); ?></select></fieldset></td> Code: [Select] <tr> <td colspan="3"><fieldset><legend>Button Text </legend><input name="text" type="text" value="<? echo $_SESSION['text'] ?>" size="50" maxlength="16" /></fieldset></td> What I need is to know howto not only produce a number of Button Text input boxes that correspond to Button No but ones that each correspond individual buttons so each button has its own text field. If anyone can help it would be much appreciated - Im suprised I have got as far as I have. here is the link at the mo http://www.d-sine.com/_STYLES/buttons.php - (the reset button will set default settings by going to a page that posts back default settings in hidden fields on a meta refresh) Kind Regards |
