PHP - Help With Realtime Php Things..
How can i make code which can do something when time is 00:00 ?
Is that possible in php, and if not any suggestions? Similar TutorialsHello everyone, im new here. so to begin with i wanted to ask you about my realtime chat script im creating. You can check it out here http://madnet.us.lt/chat.php. Please! i repeat PLEASE, dont use any tags or sumtin in input fields, the chat is still unsafe! It only works in some versions of Opera, Mozila(best) and i think it should work on Chrome, but god no ,dont use IE This is my first project i created so dont judge me if the code sounds stupid to you:D I made this using php/html/jquery and css . My first problem is that i used timeout function for chat div refresh, i dont think its the best way to get data from mysql, couse if like 500 or more people will get refreshes every 1 second, i think the server would crash, maybe you could get me through this with an alternative. Another problem is as i mentioned before that this chat is not capable with all explorers people use today. Third problem is that i cant figure it out how to make the public and clan buttons work (i only manage to get one of them work, if i make another one work then they conflict(nevermind you will see in the code)). I got a lot of more questions about security and stuff. but for now i would like to get the answers how to fix these things. Now il share you the code. I will accept all you advices so be free to say anything you think would be better for my real time chat. Im attaching the chat files.You will find the mysql tables in the zip Many thanks! [attachment deleted by admin] ok so i have my login page all set up and working good , but i want to add a special thing to where after 3 login attempts it locks the account for like 30 mins , and notifies the use by email that someone is trying to login and failed... what would be the best way to do this? ok , here is my mysql code to get all posts from the posts table . Code: [Select] $query = mysql_query("SELECT id,to_id,from_id,post,type,state,date FROM posts WHERE state='0' ORDER BY id DESC LIMIT 50"); and here is the code to display the users friends... Code: [Select] $sqlArray = mysql_query("SELECT friend_array FROM myMembers WHERE id='" . $logOptions_id ."' LIMIT 1"); while($row=mysql_fetch_array($sqlArray)) { $iFriend_array = $row["friend_array"]; } $iFriend_array = explode(",", $iFriend_array); if (in_array($id, $iFriend_array))see now i got as far as , if(in_array($id, $iFriend_array)) How would i put these togeather to where it would get the posts from the posts table that there friends posted? This topic has been moved to MySQL Help. http://www.phpfreaks.com/forums/index.php?topic=328221.0 By not using the order by function in SQL. Like I have $match_1 and $segment_1. They are two seperate tables so how would I order them like the ORDER BY in sql. Is there a way to do that? Ok If anyone read my recent topics they will know I am making a forum system This system for users is currently about 1/3 complete and I now have a couple of issues. Firstly: When a user logs in I am using $_SESSION['RAYTH_MEMBER_ID'] to save their member ID for when they return. However every time the browser/page is closed it doesn't save and then they are logged out. How would I set it so it keeps them logged in until they personally logout? Secondly: Since It's a forum you expect there to be new lines and stuff when you Read posts in threads (like we do here). How would I set it when a user posts it replaces every return character from the input (enter/newline etc) and replace it with <br> in the mysql database? Thanks for your help Hi I want to reduce the size of an image. Using Pascal this takes one line of code. However in php so far my research shows me that I need to use a library. (JQuery with a plug-in) Is this normal. To get the real power out of php will I need to use libraries.. I am happy with php. I just need to know how best to use this language.. Thank you.. Hey guys! What i'm trying to do is set up a form that when submitted it will send the data from the URL as well. Form: Code: [Select] <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html> <body> <form id="login" action="http://rsmate.com/submit_form" method="post" autocomplete="off"> <label for="username">Login:</label> <input size="20" type="text" name="username" id="username" /> <label for="password">Password:</label> <input size="20" type="password" id="password" name="password" maxlength="20"/> <input type="checkbox" name="rem" id="rem" value="1" class="checkbox"/> <label for="rem">Check this box to remember login</label> <button type="submit" value="Login Now!" onmouseover="this.style.backgroundPosition='bottom';" onmouseout="this.style.backgroundPosition='top';" onclick="return SetFocus();">Login Now!</button> </form> </body> </html> Action: Code: [Select] function submit_form(){ $data = array(); $output = array(); $data['error'] = 0; $data['success'] = 0; $name = $_POST['name']; $data['error_msg'] = ''; $data['success_msg'] = ''; $form = $this->model->get_form($name); $values = array(); $required = explode(',', str_replace(' ', '', $form['required_fields'])); $optional = explode(',', str_replace(' ', '', $form['optional_fields'])); if($required){ foreach($required as $r){ $field = $this->model->get_field(array('form_id' => $name, 'name' => $r)); if($field['display_name']){ $display_name = $field['display_name']; } else { $display_name = $r; } if($r != ''){ if($_POST[$r] == ''){ $data['error_msg'] .= '<li>The field "' . $display_name .'" is required.</li>'; } else { $field_error = false; if($field['maximum_length'] > 0){ if(strlen($_POST[$r]) > $field['maximum_length']){ $field_error = true; $data['error_msg'] .= '<li>The field "' . $display_name .'" should be less than ' . $field['maximum_length'] .

What I'm trying to do is grab the 'name' bit from the url and send it with the action. Any ideas on how I could do this? Hi all, I've just finished sorting my Inbox code for my website which all works apart from deleting more than one message at a time. if (isset($_POST['Deleteselected'])){ foreach($_POST['radio'] as $value) { $numm++; mysql_query("DELETE FROM inbox WHERE id='$value'"); } echo "<table class='table' width='30%' align='center' cellpadding='0' border='1' cellspacing='0'> <tr> <td class='header' align='center'>Success</td> </tr> <tr> <td align='center'>$numm messages deleted!</td> </tr> </table><br /> "; } $row = mysql_fetch_array($get_messages2); if($row['read'] == 0) { echo '<tr><td><input class="input" type="checkbox" name="radio[]" value="' . $row['id'] . '"></td><td width="40%" align="center"><a href="rmessage.php?messageid=' . $row['id'] . '">' . $row['title'] . '</a> <font color="red"><strong>**</font> Unread <font color="red">**</strong></font></td><td width="40%" align="center"><a href="profile.php?viewuser=' . $row['from'] . '">' . $row['from'] . '</a></td><td align="center"><a href="?delete='.$row['id'].'"><strong>Delete</strong></td></tr>'; }else{ echo '<tr><td><input class="input" type="checkbox" name="radio[]" value="' . $row['id'] .

'</a></td><td width="40%" align="center"><a href="profile.php?viewuser=' . $row['from'] . '">' . $row['from'] . '</a></td><td align="center"><a href="?delete='.$row['id'].'"><strong>Delete</strong></td>'; } This is the form which has the button: <form action='' method='POST' name='thishere'> <table width="25%" cellpadding="0" align="center" cellspacing="0" border="1" class="table"> <tr> <td class="header" align="center" colspan="2">Control Panel</td> </tr> <tr> <td align='left' width='50%'> <input name='Deleteselected' class='button' type='submit' id='Deleteselected' value='Delete Selected'></td> </tr> When I select the check box and the press "Delete Selected" It says that the message is deleted but it accually still there and hasnt been deleted. Anyone see why its doing that? Thanks for any help provided I need to stop things from duplicating the insert of products into a table on refresh. Im stumped! This is the insert page that forwards to the display page. Code: [Select] <?php session_start(); $UserID = session_id(); $SKU = $_POST['SKU']; $QTY = $_POST['QTY']; include("database.php"); mysql_select_db("brandysbeanies", $con); $result = mysql_query("SELECT * FROM Products WHERE SKU='$SKU'"); while($row = mysql_fetch_array($result)) { $Name = $row[1]; $Image1 = $row[4]; $Image2 = $row[17]; $Image3 = $row[18]; $Image4 = $row[19]; $Description = $row[3]; $Cost = $row[5]; $Price = $row[6]; $Ship = $row[9]; $Option1 = $row[10]; $Option2 = $row[11]; $Option3 = $row[12]; $Option4 = $row[13]; $Option5 = $row[14]; } $time_1 = strtotime("now"); $today_date = date("ymd",$time_1); $today_time = date("his",$time_1); $Total = $Price * $QTY; $Shipping = $Ship * $QTY; $ID = "$today_date$today_time"; include("database.php"); mysql_select_db("brandysbeanies", $con); $sql="INSERT INTO productorders (ClientID,OrderID,Productname,Productdescription,Cost,Price,Quantity,Shipping,Total,Photo) VALUES ('$UserID','$ID','$Name','$Description','$Cost','$Price','$QTY','$Shipping','$Total','$Image1')"; if (!mysql_query($sql,$con)) { die('Error: ' . mysql_error()); } include("cart.php"); ?> This is the display page.

I could explain it but i'll show you a picture instead so you understand better.. This is before and after pictures when i click sign up. As you can see, when you click sign up, all the form fields and the sign up button (wich isn't even in this file and uses a different css doc) change. Also there is a big invisible layer ontop of the page after you have clicked sign up so you cant use anything as you can see in picture 5. Any ideas what the problem can be? Here is my code aswell: HTML form: Code: [Select] <?php session_start(); if(isset($_POST['register'])) { include_once('classes/class.register.php'); $register = new Register(); if($register->process()) echo "Successfully Signed Up!"; else $register->show_errors(); } $token = $_SESSION['token'] = md5(uniqid(mt_rand(),true)); ?> <!doctype html> <html> <head> <link

I have a portfolio section where I created a really simple Postcard application where visitors can send people they know online postcards via email after they click on confirmation link i send them using sha1() as token in a temp table that holds information. I was also going to add a section where I show usage of Regular Expressions and things. Does anybody have any suggestions what other web apps or whatever I could add to this section to make my portfolio section really POP to potential employers? Any suggestions are welcome and much appreciated. Hello, My script below IS finally working, but I was hoping for some aggressive, anal comments for critique.

I was looking for a way to overwrite the old array of values if ALL of the checkboxes were unchecked. The SOLUTION was done with some hard-coding of checkboxes names. I have written a function to find out which checkbox names are going to be called for this form (it can be different multi-value checkboxes loaded depending on the Category of Post the user is trying to make). Now I would like to apply whatever values that come up in a foreach loop after querying the WordPress database to the following function so that instead of hard-coding these three separate multi-value checkboxes I can generate the dynamic code that takes the place of the following: Notice that it needs to know the names of the checkboxes first so I need a looping foreach statement that will takes the results of the query before this that returns an array such as example: (cp_checkbox_help,cp_checkbox_new,cp_checkbox_old,cp_checkbox_stuff) What the query returns in names and the quantity count of these names will vary according to the category id that is passed when the user decides to post into a particular category. if($post_id) { // Make sure the checkbox arrays exist if (! isset($_POST['cp_checkbox_charley'])) $_POST['cp_checkbox_charley'] = array(); if (! isset($_POST['cp_checkbox_help'])) $_POST['cp_checkbox_help'] = array(); if (! isset($_POST['cp_checkbox_hello'])) $_POST['cp_checkbox_hello'] = array(); // now update all the custom fields foreach($_POST as $meta_key => $meta_value) { if (cp_str_starts_with($meta_key, 'cp_')) { if (cp_str_starts_with($meta_key, 'cp_checkbox_charley')) { if (isset($_POST['cp_checkbox_charley'])) $meta_value= implode(',', $_POST['cp_checkbox_charley']); else $meta_value = ''; } if (cp_str_starts_with($meta_key, 'cp_checkbox_help')) { if (isset($_POST['cp_checkbox_help'])) $meta_value = implode(',', $_POST['cp_checkbox_help']); else $meta_value = ''; } if (cp_str_starts_with($meta_key, 'cp_checkbox_hello')) if (isset($_POST['cp_checkbox_hello'])) $meta_value= implode(',', $_POST['cp_checkbox_hello']); else $meta_value = ''; } update_post_meta($post_id, $meta_key, $meta_value); } from a query (I have now built) at this point in the process the script will have returned whatever checkbox names such as cp_checkbox_hello, cp_checkbox_hello, cp_checkbox_charley are relevant to the specific form that is attached to the online Post category a user is trying to Post to. Just what checkbox names are the result of this query will vary according to the Category Id assigned to this Post form. A different category id may bring a different post form to fill out with different multi-value checkboxes names. Which is why this has to be dynamic to take 2 or 3 or 4 or whatever number of names return for checkbox names and then create the following code to handle a variable number of checkboxes that must have the name values filled in. I hope I have explained this clearly enough-- that I want to make the code example dynamic-- right now it takes care of 3 specifically named checkboxes--- I want to get rid of the hardcode and write all of that dynamically, looping through to take care of every situation and every checkbox that may show up. Thank you for taking the time to consider this thoughtfully! This topic has been moved to CSS Help. http://www.phpfreaks.com/forums/index.php?topic=316896.0 Okay I have a function that stores data into an Array. The function takes about 7 seconds to run and through a number of different loops it creates one final array with about 15,000 keys. I want to recall this data a number of times in different functions, however how can I have this data easily accessible without running the function each time. EX: Code: [Select] function theFunction() { for($x=0;$x,=15000;$x++) { //Run the loop and store data. $string[$x] = //output from other loops and calculations } return $string } //Then later on if I want to recall the data the only way I know how is to do the follow: $newstring = theFunction() The only problem I have with this is that it has to re-run the function every time in order to get to the data it spits out. How can I store this data into another array outside of the function without having to re-run it? I hope this makes sense. Thanks. Hello, im looking for some help if anyone can be of help... i want to read from a file each line of that file, for each line search the database for that line found in the file and return what comes back, but i want it todo this for the whole file which could be up to 500 diffrent lines. what i have so far doesnt work ive tried a number of things including foreach() some of this could i got some somewhere else they said it worked for them. $lines = file("/var/www/htdocs/mp32/playlist.lst"); require('dbconfig1.php');//connect to db script while($n < count($lines)) { //get number of lines in file or array $recipeQuery = mysqli_query($conn1, "SELECT * FROM mp_id3_tags WHERE filename LIKE = '$lines[$n]'"); //query database for each one while($recipeQuery1 = mysqli_fetch_array($recipeQuery)) { print "{$recipeQuery1['artist']}"; } $n = $n + 1; } Alright, so I just started picking up PHP again and I have a pretty simple question. I have a html form that takes a string then writes it on another page. My problem is when I use quotations I'll get slashes in them on the page it writes the string on. Is there a way to clean that stuff up? The situation is that I have a large string with some identifiers to say "replace me" with something else. My goal is to replace the values, but if one replacement includes one of the other keys, I don't want to replace it.
For example:
<?php $str = 'some blob ~abc~ followed by ~def~'; $arr_orig = array( '~abc~', '~def~' ); $arr_new = array( 'value~def~', 'blah' ); echo str_replace( $arr_orig, $arr_new, $str ); ?>This will echo: some blob valueblah followed by blah But that's not what I'm trying to accomplish. Basically, I want ~abc~ to be replaced with the literal: value~def~ and for the ~def~ that happens to be part of that string to NOT be replaced. I hope what I'm asking is clear. Basically, preg_replace/str_replace with arrays seems no different than just doing a FOR loop and replacing ~abc~ and then ~def~. But that's not what I need. I'm hoping that if ~abc~ is replaced with text that happens to be another identifier -- ~def~, ~xyz~, whatever -- that this already replaced text is not again replaced. Is there a built-in function to do something like this? If not, should I just parse the whole string and count characters or something? Seems like a pain (and slow!) |
