PHP - Sticky Logic?
Hey guys, I have a question that you can hopefully help me with, I'm writing a simple forum, and I'm wondering how I would go by handling a thread that has been 'stuck' so that it isn't moved when more threads are made. I could use some a push in the right direction thanks.
Similar TutorialsWhy is my First Name text box not "sticky" when my Form reloads due to data validation errors? Here is a snippet... Code: [Select] <!-- First Name --> <li> <label for="firstName"><b>*</b>First Name:</label> <input id="firstName" name="firstName" type="text" maxlength="20" value="<?php if(isset($firstName)){echo htmlspecialchars($firstName, ENT_QUOTES);} ?>" /><!-- Sticky Field --> <?php if (!empty($errors['firstName'])){ echo '<span class="error">' . $errors['firstName'] . '</span>'; } ?> </li> I was certain that this was working before, but who knows?! At the top of the same file if my Form Handling PHP code. Here is a snippet... // ************************************************************* // HANDLE FORM. * // ************************************************************* if ($_SERVER['REQUEST_METHOD']=='POST'){ // Form was Submitted (Post). // Initialize Variables. $_SESSION['resultsCode'] = ''; $errors = array(); // Trim all Form data. $trimmed = array_map('trim', $_POST); // Connect to the database. require_once(WEB_ROOT . 'private/mysqli_connect.php'); // ************************ // Validate Form Data. * // ************************ // Validate First Name. if (empty($trimmed['firstName'])){ $errors['firstName'] = 'Please enter your First Name.'; }else{ if (preg_match('#^[A-Z \'.-]{2,20}$#i', $trimmed['firstName'])){ $firstName = $trimmed['firstName']; }else{ $errors['firstName'] = 'First Name must be 2-20 characters (A-Z \' . -)'; } } Thanks, Debbie hi, I have a form in which some information is required but the username is optional however if it is left blank it says that username is taken please choose another one. how can I make it accept it if a username isn't entered?

The footer sticks to the bottom of the window, not the bottom of the document. I need it to be the bottom of the document.

The code here is suppose to allow the user to match up a word ($word) with a list of definitions ($word_defs). I can't get the list of definitions to stick. When the user does make a guess it shows that he is always correct. How can i fix these problems? Outside entry code: Code: [Select] <?php require_once "include/session.php"; require_once "include/word_defs.php"; $word = array_keys($word_defs); $word_defs = array_unique(array_values($word_defs)); $params = (object) $_REQUEST; $session = new Session(); if (isset($params->guess)) { $word = $params->word; if ( $params->word == $word_defs[$term] ) { $response = "correct"; } else { $response = "incorrect"; } $choices->word_def[$params->word_def] = "selected"; } else { $word = $word[ rand( 0, count($word)-1 ) ]; } ?> Body code: Code: [Select] word: <?php echo $word ?> <form action="?" method="get"> definition: <select name="word_defs"> <?php foreach ($word_defs as $word_def): ?> <option <?php echo $choices->word_def[$word_def] ?> ><?php echo $word_def?></option> <?php endforeach ?> </select> <input type="submit" name="guess" value="Guess" /> <input type="hidden" name="word" value="<?php echo $word?>" /> </form> <h3><?php echo $response ?></h3> I am having an issue with the data from page ID 5 not displaying in the form, Why <?php include('includes/header.php'); include('includes/class/class.form.php'); include('includes/class/class.page.php'); $iPageID = 5; if(isset($_GET["PageID"])){ $iPageID = $_GET["PageID"]; } $EditedPage = new Page(); $EditedPage->loadPage(5); $apageInformation = array(); // Information From DB Sticky $apageInformation["name"] = $EditedPage->getPageName(); $apageInformation["content"] = $EditedPage->getPageContent(); $formEdit = new Form('editpage.php?PageID=".$iPageID', 'EditPage','return CheckEditPage();',''); $formEdit->setStickyData($apageInformation); if(isset($_POST["submit"])){ $formEdit->setStickyData = $_POST; $formEdit->checkNotEmpty("Name"); $formEdit->checkNotEmpty("PageContent"); if($formEdit->getValid() == true){ $EditedPage->setPageName = $database->escape_value($_POST["Name"]); $EditedPage->setPageContent = $database->escape_value($_POST["PageContent"]); $EditedPage->savePage(); $Message = "Page Updated"; }else{ $Message = "You Have An Error Mate"; } } $formEdit->openFieldset(); $formEdit->makeInputBox("Name","Name","CheckInput(this.id);"); $formEdit->makeTextArea("Content", "PageContent", "20","70", "CheckInput(this.id);"); $formEdit->makeSubmitButton("submit","Edit Page"); $formEdit->closeFieldset(); $newNavigation = new Navigation(); ?> <?php echo $newNavigation->mainMenu();?> <h1 class="Heading">Edit Page</h1> <?php echo $Message ?> <?php echo $formEdit->getHTML(); ?> <?php include('includes/footer.php')?> Hi, I'm trying to make a form sticky but when I display it on the web I get a blank page.

Code: [Select] <!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>Untitled Document</title> </head> <body> <?php $errors=array(); if(isset($_POST['submit'])){ validate_input(); //checks for empty fields if(count($errors) !=0){ display_form(); } else { display_form(); } } function validate_input(){ global $errors; if($_POST["name"] == ""){ $errors['name']="<font color='red'> please enter your name </font>"; } } function display_form(){ global $errors; ?> <form action="" method="post"> Name: <input name="name" type="text" size="10" maxlength="10" value = "<?php echo $_POST[name]; ?>"/> <br /> <?php echo $errors['name']; ?> <br /> Email: <input name="email" type="text" size="15" maxlength="30" /><br /> <input name="submit " type="submit" value="submit " /> </form> <?php } ?> </body> </html> I have a file sharing script, where each file has a certain number of points. I need to subtract a set number of points from the total. I'm unsure about the logic of it. This is how I total the number of points: Code: [Select] <?php $fq = "SELECT * FROM `files` WHERE owner='$username' AND active=1"; $fw = $sql->query($fq); $reward = 0; while($fr = $fw->fetch_assoc()){ $reward = $fr['points'] + $reward; }?> I'm thinking I should use a loop, while a the number to subtract is greater than or equal than 0. Can anyone help? I want to ask the user questions by using a form. I have a text field where the user inputs either 1 or 2 and then they press submit. I can get this to work but I need to keep asking them questions based off there last answer to the previus question.
I am making a game where you start with a number ex 5 and then you either choose to take away 1 or two from that number. so we take away 2 now the number is 3 and then the computer has his go using the same number. He chooses to take away 1 which makes the number 2. Now we take away 2 and win the game for being the first one to get the number down to 0. Its a very simple game that im trying to do just to brush up on my php skills.
my code so far....
<p> please enter a number to begin the subtraction game</p>
<form name="submit1" method="post">
<input type="text" name="startingNumber">
<input type="submit" name='submit1'>
</form>
<?php if (!empty($_POST['startingNumber'])) {?>
<p>your starting number is: <?php echo $_POST['startingNumber']?></p>
<?php
while(!$_POST['startingNumber'] == 0){?>
<p> Would you like to minus one or two from <?php echo $_POST['startingNumber'];
?></p>
<form name="submit2" method="post">
<input type="text" name="oneOrTwo">
<input type="submit" name='submit2'>
</form>
<?php } }?>
As you can see i am no where near close to getting this right. Im thinking i have to use a while loop to keep asking the question minus 1 or 2 until they reach 0. Inside this while loop im thinking i need something like a waituntil user has clicked submit.
In fact i have written the same game in c++ so if it helps here is that. (it works just how i want it too)
the problem im having is that in c++ you can use cin to get a input from the user and it waits until the user types in a value but im struggling to find anything like that in php.
Any help would be greatly appreciated thank you.
#include <cstdlib>
#include <iostream>
using namespace std;
int main(int argc, char *argv[])
{ int number, oneOrTwo, remainder;
cout << "please enter a number to begin the subtraction game";
cin >> number;
while (number != 0){
cout <<"your turn, subtract 1 or 2 from " << number << endl;
cin >> oneOrTwo;
if (oneOrTwo == 1 || oneOrTwo == 2){
number = number - oneOrTwo;
}else{
cout << "sorry you have entered a incorrect number. Please enter either 1 or 2" << endl;
continue;
}
if (number == 0){
cout << "congratulations! you won the game";
break;
}
remainder = number % 3;
if (remainder % 3 == 0){
remainder = 2;
}
cout << "now my turn im going to subtract " << remainder << " from " << number << endl;
number = number - remainder;
if (number == 0){
cout << "sorry the computer won this time";
}
}
system("PAUSE");
return EXIT_SUCCESS;
}
Edited by yacobm8, 16 May 2014 - 12:14 AM. Logic problem: Current directory listing at: http://www.nmlta.org...member_list.php shows the format I need. The only way I have previously been able to accomplish that format is by running four separate queries in a loop, which I understand is not good. Trying to simplify this, I need to explain my data. There are companies, and contact people at those companies, and some companies have branches, and most branches have contact people at them.
There are four tables: company, co_contact, branch, br_contact. The company, co_contact and branch tables all have a field called “company_id” to match the ones that go together, and the branch table also has a “branch_id” field to match with the people in the br_contact table.
I am successful with running separate JOIN queries for company/co_contact matching on “company_id”, and for branch/br_contact matching on “branch_id”, and have successful processes for listing the data properly.
My problem is I can’t find the logic to run them all in one query or loop that will produce the desired output I’m getting with my current four-query mess. The process should go like this:
List company1 info
List all contacts at company1
List branch1 connected to company1 (if applicable)
List all contacts at branch1 of company1
List branch2 connected to company1 (if applicable)
List all contacts at branch2 of company1
Etc. until all branches are listed for company1
Start over with company2…
Here is the code for my first attempt:
<?php
function listCompany($row) {
echo $row['comp_name'],"<br />";
if (!empty($row['comp_uw'])) {
echo $row['comp_uw'],"<br />";}
echo "</b>",$row['comp_street'],"<br />";
if (!empty($row['comp_pobox'])) {
echo $row['comp_pobox'],"<br />";}
echo $row['comp_csz'],"<br />";
echo $row['comp_ph'],"   Fax: ",$row['comp_fx'],"<br />";
if (!empty($row['comp_tfree'])) {
echo "Toll Free: ",$row['comp_tfree'],"<br />";}
if (!empty($row['comp_email'])) {
echo "Email: <a href='mailto:",$row['comp_email'],"'>",$row['comp_email'],"</a><br />";}
if (!empty($row['comp_web'])) {
echo "<a href='http://",$row['comp_web'],"' target='_blank'>",$row['comp_web'],"</a><br />";}
echo "</p>";
}
function listBranch($row2) {
if (!empty($row2['br_name'])) {
echo "<p>     <b>",$row2['br_name'],"</b><br />";}
echo "     ",$row2['br_street'],"<br />";
echo "     ",$row2['br_csz'],"<br />";
echo "     ",$row2['br_ph'],"   ",$row2['br_fx'],"<br /></p>";
}
function listContact($row) {
if (!empty($row['cont_name'])) {
echo "<p>     <b>",$row['cont_name'],"</b>, ",$row['cont_title'],"<br />";}
if (!empty($row['cont_email'])) {
echo "     Email: <a href='mailto:",$row['cont_email'],"'>",$row['cont_email'],"</a><br />";}
echo "</p>";
}
function listBranchContact($row2) {
if (!empty($row2['cont_name'])) {
echo "<p>          <b>",$row2['cont_name'],"</b>, ",$row2['cont_title'],"<br />";}
if (!empty($row2['cont_email'])) {
echo "          Email: <a href='mailto:",$row2['cont_email'],"'>",$row2['cont_email'],"</a><br />";}
echo "</p>";

?>
My first thought was to insert the "if ($row[next($row['company_id'] != $lastCompany)]) {" qualifier after listing the contact for the company being processed, that way when I know a new company is on the next row, I can pause and run my second query to find any applicable branches that match the current company_id. The syntax must be wrong the way I have it, because I get an error with this, saying: "Fatal error: Only variables can be passed by reference in..." referencing that call in my code. I don't know if there is a syntax change that would make this work, or not.
I have thought about, and tried different ways to run a query using JOIN on all four of my tables, but the resulting rows do not correspond with the order in which I need to process them, if that makes sense. I am not opposed to any suggestions that will make this work - I just can't seem to think it through and find the correct solution, if there is one. The difficulty seems to me to be that the process of listing company/contact info needs to know when it has reached the last row containing a contact tied to the company, so that the branch routine can be processed for the same company. Any help or suggestions would be appreciated. Thanks!
Hi all, Its been a while since I looked at PHP and I have forgotten some basics What I am trying to achieve is display category names, sub categories and results into a list Code: [Select] <ul id="nav"> <li><a href="#">Main Cat</a> <ul> <li><a href="#">Sub Cat 1</a> <ul> <li><a href="#">result</a></li> <li><a href="#">result</a></li> </ul> </li> <li><a href="#">Sub Cat 2</a> <ul> <li><a href="#">result</a></li> <li><a href="#">result</a></li> </ul> </ul> </li> What would be the best way to organise my database? Have everything in one entry like: main_id / sub_id / listing_id / listing_name or separate them into a table for cats, one for sub cats and what parent it belongs to, then a table for the listings linking to the sub cat it belongs to? I have confused myself no end on how then to display the results, so any help with would be gratefully received! Thanks Dave i have two multi-dimensional arrays that i'd like to manipulate to check a few things. Their structures are different and i'm giving myself headaches trying to think through this. I have a $sums array which has information on a product in a purchase order. The second array consists of items(products) that are going to update the purchase order. So the first array key of $sums correlates with the "order" of the $items array. I'd like to write a function that: 1. Makes sure the first array key of $sums exists as an "order" value in the $items array. 2. Makes sure the $items price is greater than the $sums price Code: [Select] <?php $sums['23']['collected']['price'] = 30; $sums['73']['collected']['price'] = 60; $sums['89']['collected']['price'] = 90; $items['abc123']['order'] = '23'; $items['abc123']['price'] = 14; $items['321cba']['order'] = '73'; $items['321cba']['price'] = 79; function check_items($sums,$items) { $error = ""; //Makes sure the first array key of $sums exists as "order" value in the $items array. //If not -> $error = "Item #".$key." is not found in the items array."; //where $key is either the first array key of $sums or the "order" value in $items because they are the same thing //if found in $sums if($items[$hash]['price'] < $sums[$items[$hash]['collected']['price'] ) { $error = "Item #".$items[$hash]['order']."'s price must not be lower than ".$sums[$items[$hash]['order']]['collected']['price']; } return $error; } // $sums['23'] would cause an error because its price of 14 is less than 30 // $sums['73'] would pass because it exists in $items and its price of 79 is greater than the $sums price of 60. // $sums['89'] would cause an error because there is no $item corresponding to it ?> I just don't know where to put the foreach loops or where to even start really :/ I am trying to understand PHP While Loops. For example. $info=mysql_fetch_array($query); will create an array of a mysql query. how does while($info=mysql_fetch_array($query) { echo $info['1']; } ensure that each element of the array is echoed. It seems that $info is a one time statement that grabs an array, how does adding While make it capable of being extended into rows? To me this says While this is true, do this. But if it is true once, how does PHP know when to stop? Any help would br GREAT! This Post is about Sticky Forms and How to get them working. I would like to record the users input after processing it. I have the processing page redirecting back to the form page. I have been trying and trying and trying some more to re-display the users input, so they don't hav eto keep entering the same crap ova & ova. I would imagine this must be done using sessions given I am not using PHP Self fuction.. Here's what I have that does not work at all :-) This first code is on the process page. Code: [Select] <?php ob_start(); session_start(); $itemDescription=$_POST['itemDescription']; $itemPrice=$_POST['itemPrice']; $itemQty=$_POST['itemQty']; $bidderId=$_POST['bidderId']; $totalPrice=$_POST['totalPrice']; mysql_connect("$host", "$db_user", "$db_password")or die("cannot connect to server"); mysql_select_db("$db_name")or die("cannot select DB"); if (isset($bidderId)) { $totalPrice=$itemQty * $itemPrice; mysql_query("INSERT INTO transactions (itemDescription, itemPrice, itemQty, bidderId, totalPrice) VALUES('$itemDescription', '$itemPrice', '$itemQty', '$bidderId', '$totalPrice')") or die(mysql_error()); $_SESSION['itemDescription']='$itemDescription'; header("Location: attendance.php"); exit(); } else echo "<font face= \"calibri\" size= \"3\" color= \"red\">You have left a field blank, please press your browsers back button. </font>"; exit(); ob_end_flush(); ?> Now How do I display the users input back to the form? Code: [Select] <?php session_start(); $itemDescription = ""; //item description, default as blank ?> <form action="record_trans.php" method="post"> <font face= "calibri" size= "4"> <table> <tr> <td><b>Item Description:</b></td> <td><input type= "text" name= "itemDescription" size= "30" value="<?php echo $itemDescription;?>"></td> </tr> <tr> <td><b>Item Price:</b></td> <td><input type= "text" name= "itemPrice" size= "5" value="<?php echo $itemPrice;?>"> </td> </tr> </tr> <td><b>Winning Bidders:</b></td> <td><input type="text" name= "bidderId" size= "5" /> </td> </tr> <tr> <td><b>How many deals?:</b></td> <td><input type="text" name= "itemQty" size= "3" value= "1" /></td> </tr> </table> <br/> <center><input type="submit" name="submit" value= "Save & Cont."

Some forum users here gave me great help yesterday in working with dropdown menus. In fact, I need quite a few of these dropdown menus in several forms over several pages, so I created several simple arrays and made a function to create the dropdowns. Here's one of my arrays: Code: [Select] <?php $instruments = array( 'Bassoon', 'Cello', 'Clarinet', 'Double Bass', 'Flute', 'French Horn', 'Oboe', 'Percussion', 'Trombone', 'Trumpet', 'Tuba', 'Viola', 'Violin', 'Other' ); Here's my function: Code: [Select] <?php function create_dropdown($array_name, $array_item) { echo "<select name='$array_item'>\n"; echo "<option value='select'>Select…</option>\n"; foreach( $array_name as $v ) { echo "<option value='$v'>" . $v . "</option>\n"; } echo "</select>\n"; } ... and anywhere I need a dropdown menu, I'm calling it like this: Code: [Select] <?php create_dropdown($instruments, 'instrument'); The dropdown menus, however (in some fairly detailed forms for my local youth orchestra's site), need to be sticky. How can I modify my function, above, so that the selected value will be retained if there are other form submission errors when the form is submitted? I have tried endlessly today but to no avail... If you can help while I still have some hair left, I'd be greatly appreciative. since many do not know the term sticky = when a form is submitted, the data contained is not deleted but instead last checked data will be shown. I have some dynamically generated checkboxes from the database. I tried the below code to make them sticky but they are simply preselected in stead of becoming sticky. What am I doing wrong? <?php $sql2 = "SELECT relation FROM table_rel_info"; $result2 = @mysqli_query($dbc, $sql2); while($row2 = mysqli_fetch_array($result2, MYSQLI_ASSOC)) { echo "<label>" . $row2['relation'] . "</label>"; echo "<input class='box' type='checkbox' value=1"; ?> <?php if (isset($row2['relation'])) { echo 'checked="checked"';}?> <?php echo "'/>" . "<br />"; } ?> Hey all, I'm somewhat new to PHP and working on a form and trying to make radio buttons sticky. I've tried the following but when I refresh/got back to the page then now matter what button I chose it always shows the "4" bedroom or "No". What size of unit do you require? <input type="radio" name="unitsize" value="1 Bedroom" <?php if (isset($_POST['unitsize']) == '1 Bedroom') echo 'checked'; ?>> 1 bedroom <input type="radio" name="unitsize" value="2 Bedroom" <?php if (isset($_POST['unitsize']) == '2 Bedroom') echo 'checked'; ?>> 2 bedroom <input type="radio" name="unitsize" value="3 Bedroom" <?php if (isset($_POST['unitsize']) == '3 Bedroom') echo 'checked'; ?>> 3 bedroom <input type="radio" name="unitsize" value="4 Bedroom" <?php if (isset($_POST['unitsize']) == '4 Bedroom') echo 'checked'; ?>> 4 bedroom Do you require an accessible unit?</td> <input type="radio" name="accessible" value="Yes" <?php if (isset($_POST['accessible']) == 'Yes') echo 'checked'; ?>> Yes <input type="radio" name="accessible" value="No" <?php if (isset($_POST['accessible']) == 'No') echo 'checked'; ?>> No Any help or suggestions are greatly appreciated. I'm trying to get this drop down menu to be sticky once the user clicks submit. Here's my entry code: Code: [Select] if (isset($_POST['guess'])) { if ($_POST['guess'] == $_SESSION['number']) { $response = "You Win!"; unset($_SESSION['number']); } else { $_SESSION['tries']++; if ($_SESSION['tries'] < 3) { $response = "Try #{$_SESSION['tries']}<br /><br />"; } else { $response = "You Lose"; unset($_SESSION['number']); } } } if (empty($_SESSION['number'])) { $_SESSION['tries'] = 0; $_SESSION['number'] = rand(1, 10); } And in my body: Code: [Select] <select name="guess" id="guess"> <?php for ($i = 1; $i < 11; $i++) { echo "<option value='{$i}'>{$i}</option>"; } ?> </select> I want a Text Area on my form where I can enter the body of an article. It should be sticky so the input is not lost if there are form issues and the form has to be re-loaded. The problem is that when I type "mmm" into this field, after I click "Submit" my form is reloaded - because I didn't complete it - and several blank lines appear before and after the text "mmm"?! Here is my code... Code: [Select] <!-- Body --> <li> <label for="body"><span class="required">*</span>Body:</label> <textarea id="body" name="body" class="text" cols="20" rows="5" wrap="soft"> <?php if(isset($body)){echo htmlentities($body, ENT_QUOTES);} ?> </textarea> <?php if (!empty($errors['body'])){ echo '<span class="error">' . $errors['body'] . '</span>'; } ?> </li> What seems to be the problem?! Debbie I have PHP code that generates a long list of Birth Years in a Drop-down list, and I want to make the control "sticky". I know how to make something like this sticky - thanks to help from you guys... Code: [Select] <!-- Gender --> <label for="gender">Gender:</label> <select id="gender" name="gender"> <option value="">--</option> <option value="F"<?php echo (isset($gender) && $gender == "F") ? 'selected="selected"' : ''; ?>>Female</option> <option value="M"<?php echo (isset($gender) && $gender == "M") ? 'selected="selected"' : ''; ?>>Male</option> </select> But my Birth Year code is a little more complex and I'm racking me brain how to do it... Code: [Select] <!-- Birth Year --> <label for="birthYear">Year Born:</label> <select id="birthYear" name="birthYear"> <option value="">--</option> <?php // Display dates for Users between 18 and 100. for($i = $newestYear; $i >= $oldestYear; $i--){ echo '<option value="' . $i . '">' . $i . '</option>'; } ?> </select> How do I make this second set of code "sticky"?? Thanks, Debbie |
