PHP - Use Of Php For Simple Client Side Apps
I was wondering about developing simple client side graphical apps.
I was thinking of using php with an ODBC connection to the data store.
The data store might be a text file in CSV format or something similar. (maybe even a spreadsheet)!
I was wondering what would be a very simple minimally useful web server to run on the client?
The client would probably be MS Windows XP/7.
What are your thoughts?
Similar TutorialsI have a web portal which is scripted using client side scripting language i.e HTML. I want to create a login page in .php and want the other pages to be in .hmtl. Can i do so? I want to do this because i want the login password to be stored in a database. Also I want the password to get encrypted (by either MD5 javascript or OpenSSL ) when user enters it inside the login form. I cannot create the entire portal in php because my portal makes use of C code. And php doesn't have an interface with C language. Can a user get directed to a .html page after a secure login from login.php page ? My main aim is to secure the access to my web portal using a password. I tried to authenticate the login using javascript where the password was stored in an array. But i feel any one having moderate knowledge can easily break that password. Any help would be greatly appreciated!! is it true that all the server side code runs before the client side code when accessing a webpage? if that is true, what about PHP code that is embedded inside HTML tags? wouldn't that result in an error a lot of times? I wish to create validation rules once which are used both on the client and on the server.
For instance, I will start off with the following PHP object:
stdClass Object
(
[rules] => stdClass Object
(
[email] => stdClass Object
(
[required] => 1
[email] => 1
[remote] => stdClass Object
(
[url] => check-email.php
[type] => post
[data] => stdClass Object
(
[username] => function() {return $( '#username' ).val();}
)
)
)
)
[messages] => stdClass Object
(
[email] => stdClass Object
(
[required] => an email is required
)
)
)
When the edit page is downloaded to the client, I will include this object in some format suitable to the client.
The client will then use the jQuery Validation plugin (http://jqueryvalidation.org/) along with the validation object, and client side validate the page.
When the form passes client side validation and is uploaded, PHP will use the same validation object to serverside validate the form (I have this part working as desired).
My question is how should I pass this data to the client? Originally, I would just use PHP to write some JavaScript.
exit('var myObj='.json_encode($myObj));
Note that when I json_encode the object, the value of $myObj->rules->email->remote->data->username is a string with quotes around it, however, I can easily use PHP to strip these tags before sending it to the client.
As Jacques1 pointed out in http://forums.phpfre...ascript-client/, I should never ever use PHP to generate JavaScript, and should use AJAX to download the JSON directly. I tried doing the later, but found that a callback function could not be included in the JSON.
Please advise on the best way to accomplish this.
Thank you
I'm in the habit of verifying input client side. For example, there is a field to enter a number, and I ensure that it is within a particular range using Javascript. My backend PHP code does not do such checking... Is this bad? Should I be doing checking using my backend code and send a response back to the client to display a message? Admittedly, I avoid it, since it's a little extra work -- well more extra than just javascripts, IF-THEN-ALERT type statement. Hello guys. I was thinking on posting this under the mysql thread. but i think this can be solved by php.. anyway, i want to dump mysql data on the client side whenever a user logs out. how can i do this? thanks in advance. We have a website that allows the user to upload his/her picture so we use the ftp_put() command. I use Code: [Select] <?php $path = getcwd(); echo $path; ?> This is the output: Code: [Select] /home/vol10/000a.biz/a000b_7363341/htdocs/gankgame to determine the absolute path where my website is stored. My website "CAN" connect to the ftp server but it can't upload files. Uploading always fail. I can't determine the right path. "My code is attached" I want to do simple client side validation but I don't know Javascript. Can someone point me to an easy example on how to implement or post something here? Is it possible adding a button with PHP, which could be used for adding an optional text input field by client side user? My purpose is actually very simple: The client side users could be free creating and adding more and customized variables, which are intended to be used as strings and related or associated variables. So, am I able to do these kind of tasks simply using PHP alone? Or, should I use some JavaScript like technologies to make those functions available in real world's practices? Hi All - I'm trying to see if the below is possible using PHP. is it possible for php to allow a user to check if a port is open/listening on a remote server/PC, from their local machine. I've seen scripts on the web that talk about opening cmd.exe - this won't work as not all of my users will be on windows. Also saw fsock.. but the remote server is not serving http page(s). Also saw telnet, but again, some of my users may not have that windows feature enabled. Desired workflow: 1. user enters the server hostname/IP and a port 2. my php webapp will emulate checking if that hostname and port is open from the local user's computer.
thanks! Hi This is for a simple email client. I am trying to create a delete button that deletes a message when in message view from the MySQL database. Bellow is what I have so far. Currently it sends an alert confirming the message has been deleted and goes back to the inbox view where, it is evident that nothing has been deleted. Even when I log out then back in, the message is still there. Code: [Select] // This is how I call the JavaScript function in the html page: <input type="button" value="Delete" onclick="deleteMessage();" /> // This is the relevant JavaScript: /* ~~~~~~~~~~~~~~~~~~~~~~~~~~ Functions used to Delete a message ~~~~~~~~~~~~~~~~~~~~~~~~~~ */ var requestDlt = false; // for the message to delete /* I created my own addition PHP script that, if correct, should delete a message when in message view */ function deleteMessage(mailNumber) { var url = "delete.php?mailID="+mailNumber; // assign to the url if (window.ActiveXObject) // if the users window matches this { // then requestDlt = new ActiveXObject("Microsoft.XMLHTTP"); // create a new ActiveXObject } else if (window.XMLHttpRequest) // else if the window matches this { // then requestDlt = new XMLHttpRequest(); // the global variable is an XMLHttpRequest } if (requestDlt!=null) // if the request exists { requestDlt.onreadystatechange=RequestFunctionDelete; // when ready envoke RequestFunctionMessage requestDlt.open("GET",url); // the request will now open the assigned url requestDlt.send(null); // send the request } } function RequestFunctionDelete() { if (requestDlt.readyState==4) // if all has been sent { // and if (requestDlt.status==200) // if it is all OK { /* if in message view, hide it, and show inbox */ if (document.getElementById("messageView").style.display!="none") { var response=requestDlt.responseText; // the variable response will hold the response text alert(response); // display the response to the user $("#messageView").fadeOut(1000, function() // hide message { $("#inboxBox").fadeIn(1000); // show inbox }); } else { // else /* Warn user they are unable to access button in this view */ alert("select a message you would like to delete"); } } } } // And lastly, here is the PHP Script that is called: <?php header('Content-Type: text/xml'); header("Cache-Control: no-cache, must-revalidate"); $dbhost = 'localhost'; $dbuser = 'cjc16'; $dbpass = 'cjc16'; $dbname = 'cjc16'; $dbtable = 'mail'; $id=$_GET["mailID"]; $con = mysql_connect($dbhost, $dbuser, $dbpass); if (!$con) { die('Could not connect: ' . mysql_error()); } $dbselect = mysql_select_db($dbname,$con); $sql="DELETE FROM $dbtable WHERE mailID='$id'"; $result = mysql_query($sql); if ($result) { echo "Deleted"; } else { echo 'Unable to delete'; } mysql_close($con); ?> Mod edit: [code] . . .

Then users can search for apps and "install" apps but really just have them show up on the homepage. So how would the database design work like have a field that is updated to 1 if the user has it installed and 0 if its not. And then do like an if statement to pull all the fields with 1 where username='$username'. And when it pulls it should I add like a URL field to it to so when it pulls the app information there will be a link to the app url. Could somebody please help me with what I should do because I am really confused on what design and if statements I should use
In php how could I build a .net application? So I have a source that I want to build in .net, but i'm not sure how... I just built a new app and I used the same shopping cart class I created in a previous app. This way when I add something in the old app's shopping cart, it also shows up my new app's cart Any ideas how can I solve this ? Hey all
I have been building sites for a long time and I am pretty confident in modern frameworks like Bootstrap etc. I have played about with JQuery Mobile and UI. I know how to make mobile sites from a front end side. I understand that I can upload my site to PhoneGap and turn it into a native app.
However, I would love to know how to make useful apps that dont just display static text. E.g. using things like Google Places API.
I know how to make mobile sites easily enough that display info. I just don't really understand how to link that up with dynamic data from APIs etc. How to feed that content back to the user.
For a vasic example, say I wanted to have a simple app that had a search box. You enter 'PIZZA' into it and it comes back with a result of all local pizza spots. How would I do that?
If someone could point me in the right direction for where I could experiment with this I would be really grateful . Dear Friends,
I have 3 different Applications under the same server. Please, could you help me to share info between them?
App1 is a "User Admin Application". Here the user should do the login. After the login, the User should be able to open App2 or/and App3 I have my dns set so that it uses google servers to handle my email. I have a spf record: Host: @ TXT Value: v=spf1 include:_spf.google.com ~all However if I want to send mail using the php mail function how do I do this? because it is getting seen a spam because I assume it is not being seen as coming from google servers but from my websites server?... what do I do in this case? I’m trying to write a post-panel where the user can see the preview of his post to the right of the text area he’s writing into. I tried the following into a file called writepost.php : <?php $text=(isset($_GET['message']))?$_GET['message']:''; $formatted_text=nl2br(stripslashes(htmlspecialchars($text))); echo '<form method="post" action="proceedtopost.php?>'. '<table>'. '<td style width="50%"><tr>'. '<fieldset> Write your post here : <br> <textarea cols="50" rows="12" '. 'id="message" name="message">'.$text.'</textarea>'. '</fieldset> <p> '. '<input type="submit" name="submit" formaction="writepost.php" value="Preview" /> '. '<input type="submit" name="submit" value="Sent" /> '. '</p>'. '</td>'. '<td>'. '<fieldset> Your post will appear as follows :<br><p> '. $formatted_text. '</fieldset>'. '</td></tr>'. '</table>'. '</form>';There are several things wrong with this code : 1) When the user hits the "Preview" button, I expect writepost.php to be reloaded (this is what happens), and the current content of the textarea to be stored in $_GET['message'] (this is not what happens). 2) Why does my browser output the preview part under the text area (or in other words outputs the HTML table as a single column of two cells), when I insist in my HTML code for the table to be displayed as a single row ? I like to set up websites for people who don't have the know how to do it themselves, I mainly set them up wordpress sites cuz thats pretty easy for them to modify and maintain themselves. To save myself time, I decided to learn how to do it with Composer (what a brilliant tool that it). Can anyone who uses composer for this kinda thing, can you post your composer.json files here. Also, if anyone can show me a better way of doing things, it'd be much appreciated. Heres the one I made:
{
"name": "acme/brilliant-wordpress-site",
"description": "My brilliant WordPress site",
"repositories":[
{
"type":"composer",
"url":"http://wpackagist.org"
}
],
"require": {
"johnpbloch/wordpress": ">=3.8.0",
"wpackagist-plugin/captcha":">=3.9",
"wpackagist-plugin/tinymce-advanced":">=4.0.0",
"wpackagist-plugin/wordpress-importer":"*",
"wpackagist-theme/hueman":"*",
"wpackagist-theme/eclipse":"*",
"wpackagist-theme/raindrops":"*"
},
"extra": {
"installer-paths": {
"mysite": ["johnpbloch/wordpress"],
"mysite/wp-content/plugins/{$name}": ["type:wordpress-plugin"],
"mysite/wp-content/themes/{$name}": ["type:wordpress-theme"]
}
},
"autoload": {
"psr-0": {
"Acme": "src/"
}
}
}
I think I'm doing this in a silly way though. I read about these composer installer things on github, but I didn't figure out how to use them so instead I used the installer-paths key to make the autoloader put the files in the right place. Heres a composer.json file I found which is better cuz it uses a post installation script:
{
"require": {
"wordpress/core": "3.5.2",
"wordpress/twentytwelve": "1.1",
"wordpress/akismet": "2.5.7",
"wordpress/google-sitemap-generator": "3.2.9",
"wordpress/google-analytics-for-wordpress": "4.3.3",
"wordpress/wordpress-importer": "0.6.1"
},
"repositories": [
{
"type": "composer",
"url": "https://raw.github.com/wordpressoncomposer/composer-repository/master/"
},
{
"type": "vcs",
"url": "https://github.com/wordpressoncomposer/installer"
}
],
"scripts": {
"post-install-cmd": "Wordpress\\Composer\\InstallerTasks::wpConfig"
},
"extra": {
"wordpress_coredir": "wordpress/core",
"wordpress_wp_contentdir": "wordpress/wp-content",
"wordpress_wp_config": {
"site_url": "http://localhost",
"db_host": "localhost",
"db_user": "root",
"db_pass": "",
"db_name": "wordpress"
}
},
"minimum-stability": "dev"
}
I'm gonna start using these scripts once I figure out how to use them. Where are the scripts stored? I haven't a clue what this autoload thing is all about either, is it a tool for moving files into the appropriate directories? See how the first file gets wordpress from packagist, and the second one gets it from github. Is there a difference? If I was to add that post-install-cmd key to the first composer.json file, would it still work? In other words, do both repositories contain identical packages.
need a little help guys! I use the script below to display profile images, trouble is it shows 1 on top of the other, and i need it to double up 2 profile images on top of 2 profile images ect any ideas how i can do this. require("./include/mysqldb.php"); $con = mysql_connect("$dbhost","$dbuser","$dbpass"); if (!$con) { die('Could not connect: ' . mysql_error()); } mysql_select_db("$dbame", $con); $result = mysql_query("SELECT * FROM Search_profiles_up WHERE upgrade_one ='1' ORDER BY RAND() LIMIT 40"); print "<table width=\"293\" height=\"111\" border=\"0\"> <tr>\n"; while($row = mysql_fetch_array($result)) { print "<td width=\"142\"><img src=" . $row['search_small_image'] . " width=\"144\" height=\"169\" /></td>\n"; print " </tr>\n"; print " <tr> \n"; print "<td>" . $row['star'] . "</td>\n"; print " </tr>\n"; print " <tr>\n"; print "<td>" . $row['username_search'] . "</td>\n"; print " </tr>\n"; print " <tr> \n"; print "<td>" . $row['phone_search'] . "</td>\n"; print " </tr> \n"; } print "</table>"; mysql_close($con); ?> |
