PHP - How To Create A Form With A Submit Button That Saves The Checked Box To A $_session And Create A Link To A Different Php That Takes On The $_session.
Hello everyone, I am working on a form that is similar to a shopping cart system and I am thinking of creating a button that submits the checked value and saves them to a $_SESSION variable. And also a link that links to a cart.html that takes the values of a $_SESSION variable. I am have trouble figuring what tag/attribute should I use in order to achieve that.
Right now my code attached below submits the checked values to cart.html directly. However I want my submit button to save the checked box to a $_SESSION variable and STAY on the same page. And then I will implement a <a> to link to the cart.php.
I researched a little bit about this subject and I know it's somewhat related to ajax/jquery. I just wanted to know more about it from you guys. I appreciate your attention for reading the post and Thanks!
Below is the form that I currently have:
<form name= "finalForm" method="POST" action="cart.php">
<input type="Submit" name="finalSelected"/>
<?php foreach($FinalName as $key => $item) {?>
<tr>
<td><input type="checkbox" name="fSelected[]" value="<?php echo htmlspecialchars($FinalID[$key])?>" />
<?php echo "$FinalID[$key] & $item";?>
</td>
</tr>
<?php } ;?>
Below is the code for cart.php
<?php
require ('connect_db.php');
if(isset($_POST['finalSelected']))
{
if(!empty($_POST['fSelected']))
{
$chosen = $_POST['fSelected'];
foreach ($chosen as $item)
echo "aID selected: $item </br>";
$delimit = implode(", ", $chosen);
print_r($delimit);
}
}
if(isset($delimit))
{
$cartSQL = "SELECT * from article where aID in ($delimit)";
$cartQuery = mysqli_query($dbc, $cartSQL) or die (mysqli_error($dbc));
while($row = mysqli_fetch_array($cartQuery, MYSQLI_BOTH))
{
$aTitle[] = $row[ 'name' ];
}
}
?>
<table>
<?php if(isset($delimit)) {
$c=0; foreach($aTitle as $item) {?>
<tr>
<td>
<?php echo $aTitle[$c]; $c++;?>
</td>
</tr>
<?php }}?>
</table>
Similar TutorialsHi all, here's my code: Code: [Select] <?php foreach ($_SESSION['topping'] as $value) { echo "<tr><td width='30%'>Topping</td><td width='50%'>$value</td><td width='20%'><select name='notopping'>"; foreach ($_SESSION['cupcake'] as $number) { '<option name="notoppings[]" value="'.$number.'">".$number."</option>'; } echo "</select></td></tr>"; } ?> $_SESSION['cupcake'] is a value from either 6, 12, 24 or 36. What I want to do is put them into a drop down box (second foreach) as the value and the displayed value - counting up from 1 (so 1,2,3,4,5,6 or up to 12,24 etc). Also by creating this as an array, does this mean than for each topping (say Vanilla and Chocolate) the value dynamically created can be used on the next page by using $_POST['notoppings'] to display each type (two different numbers - one for Vanilla and one for Chocolate). Does that make sense? Thanks! Jason
First let me explain my code. This is later included in project_status.php] . In project_status.php] , I have included another file project_status_app.php which contains a HTML form.
<?php
include 'inc_fn_header_and_menu.php';
function includeFile($file,$variable) {
$var = $variable;
include($file);
}
if (isset($_GET['id']) && $_GET['id']!="") {
$pid = $_GET['id'];
$_SESSION['pidForApproval'] = $_GET['id'];
$query = 'SELECT * FROM `profile` WHERE pid ='.'\''.$pid.'\'';
$result=mysqli_query($db,$queryToRetrievePP) or die("There are no records to display ... \n" . mysqli_error());
foreach ($result as $row) {
$status = $row['status'];
}
}
...........some PHP and HTML code.......
<div id="customerPurchaseApprovalForm">
<?php
echo '<p>APPROVAL FOR CUSTOMER PURCHASE</p>';
$discountApprovalStatus = "Granted";
if ($discountApprovalStatus == "Granted") {
includeFile("project_status_app.php",$highestannualvalue);
} else {
//.........
}
In project_status_app.php I am attempting to retrieve pidForApproval from the $_SESSION array.
<?php
// put your code here UPDATE `pp` SET `customer_purchase_remarks` = 'hahaha' WHERE `pp`.`id` = 207;
if ($_SERVER['REQUEST_METHOD'] == 'POST') {
include '../../inc/fastlogin.php';
$sql = "UPDATE pp SET customer_purchase_remarks ='{$_POST['remarkstxt']}' WHERE pp.pid='{$_SESSION['pidForApproval']}'";
$result = mysqli_query ( $fastdb, $sql ) ;
if (mysqli_affected_rows($fastdb) != 1) {
$_SESSION['err_cpa_rmks'] = "<p>Error while updating WHERE id='{$_SESSION['pidForApproval']}'</p>";
//echo "<p>Error while updating WHERE id='{$_POST['pidForApproval']}'</p>".mysqli_error($fastdb);
} else {
$_SESSION['suc_cpa_rmks'] = "<p>Records was updated successfully.</p>";
//echo "Records was updated successfully.";
}
header ("location: project_status.php?id="$_SESSION['pidForApproval']);
exit();
}
?>
When I load project_status.php, project_status_app.php is supposed to display the form. Once the user fills in the form the and the submit button has been pressed, the UPDATE statement is supposed to run and then it is supposed to navigate back to project_status.php?id=FA142. But the update is failing and the when the project_status.php is loaded back, the url looks like this http://localhost/fast/project_status.php?id= . The id is empty. It is supposed to be something like this http://localhost/fast/project_status.php?id=FA142. With the id being populated at the
header ("location: project_status.php?id=".$_SESSION['pidForApproval']);
Missing some information. Driving myself nuts...can't figure out what is wrong with this code. This is part of a pagination system that uses an array instead of hitting the db each time. I am using CodeLobster PHP version (3.7), Windows 7, and using a virtual server on my computer for development (XAMPP) the error I get is this: Warning: Invalid argument supplied for foreach() in C:\xampp\htdocs\website\searchinv.php on line 45 Warning: array_multisort() function.array-multisort: Argument #1 is expected to be an array or a sort flag in C:\xampp\htdocs\website\searchinv.php on line 49 Warning: array_slice() expects parameter 1 to be array, boolean given in C:\xampp\htdocs\website\searchinv.php on line 108 Warning: Invalid argument supplied for foreach() in C:\xampp\htdocs\website\searchinv.php on line 146 I am pasting the code below and point out each of the lines in the warnings above, and will try to clean up some so that it's not too extensive... Here is the problem: If I click on any of the "page" $_SESSION['rows'] has all the correct information contained in it. However, if I trigger the "re-sort" select option...$_SESSION['rows'] is empty...all my other $_SESSION variables are still there. At first I thought it was an issue with too many "if/ifelse/else" statements or a wrong syntax...so I changed it to a "switch" and traced it closely. I don't see anything wrong. Next I thought it was caused by the JavaScript "onchange" event...so I took that out...and replaced it with just a submit button...same result. I've done a search on the page for EVERY $_SESSION['rows'] and found only 4 and none of them should blank it out...I've been going crazy on this code for 2 days I'm pulling my hair out now...can ANYONE help? Code: [Select] if(!empty($_POST)) { if(empty($_POST['page'])) { switch($_POST) { case (!empty($_POST['ref'])): $deleted=sql_ending($_POST['del']); $rows=select_from_database('inventory', '*', 'ref_number=\''.$_POST['ref'].'\' and '.$deleted); break; case (!empty($_POST['type'])): $sort=$_POST['sort']; $deleted=sql_ending($_POST['del']); if($_POST['type']!='*') { $type=$_POST['type']; $len=strlen(trim($type)); if($len!=1) $type=$type.'-'; $end=$deleted.' and ref_number like \''.$type.'%\''; } else $end=$deleted; $rows=select_from_database('inventory', '*', $end, $sort); break; default: $data=$_SESSION['rows']; $sorts=explode(' ', $_POST['sort']); $keys=$sorts[0]; $order=$sorts[1]; Line 45 --> foreach ($data as $key => $row) { $column[$key]=$row[$keys]; } Line 49 --> $rows=array_multisort($column, $order, $data); break; } $_SESSION['rows']=$rows; } $x=count($_SESSION['rows']); if(isset($_SESSION['admin_user'])) $width=1280; else $width=900; $srch_rslt= ' <div id="displaybox"> <div id="translucent"></div> <div id="result" style="width:'.$width.'px;"> <!--[if lt IE 7]> <h3 class="center">This site looks much better with IE 7 and above.

Hi, how can i create a form within a form with the click of a button? so that when i click add new item, it brings form fields under the current one. hope my explanation helps thanks Code: [Select] <form id="form1" name="form1" method="post" action=""> <table width="100%" border="0" cellspacing="2" cellpadding="0"> <tr> <td width="22%">Invoice Number </td> <td width="78%"> </td> </tr> <tr> <td>Date Issued </td> <td> </td> </tr> <tr> <td colspan="2"> </td> </tr> <tr> <td colspan="2"><table width="100%" border="0" cellspacing="2" cellpadding="0"> <tr> <td width="10%">Quantity</td> <td width="70%">Description</td> <td width="9%">Taxable</td> <td width="11%">Amnount</td> </tr> <tr> <td valign="top"><input name="textfield" type="text" size="7" /></td> <td valign="top"><textarea name="textfield2" cols="80"></textarea></td> <td valign="top"><input type="checkbox" name="checkbox" value="checkbox" /></td> <td valign="top"><input name="textfield3" type="text" size="12" /></td> </tr> <tr> <td colspan="4"><input type="submit" name="Submit" value="Add New Item" /></td> </tr> </table></td> </tr> <tr> <td colspan="2"> </td> </tr> <tr> <td colspan="2"> </td> </tr> <tr> <td colspan="2"> </td> </tr> </table> </form> Hope someone can help put with this - I have inherited a site and am trying to modify some PHP that I am unfamiliar with. I have gotten so far with it, but still have a problem with it.
Its a page on an online store offering optional extras depending on the product. The products are furniture, so and there was an option to buy cushions for some. The change I am trying to make is to have an option for two different sizes of cushion depending on the product.
So there was a field 'cushions' in the product table, and a page 'accessories.php' that offered the option to add cushions.
I have added a new field 'cushions2' and a new page 'accessories2.php' to cover the new size of cushions.
The site is here, with this example product:
http://www.lloydloom...oduct.php?id=32
If you click 'Add to cart' the next page offers you the option to add custom paintwork.
If you enter something there, and click on 'Add colour to order' it works - i.e. the next page is the one offering the cushions.
But if you just click on 'No thank you, proceed with order' it just reloads the page - basically the URL isn't being puled through as it should be.
On that page the PHP at the top of the page looks like this:
<?php session_start(); i have an html form which is a "post" on it i have an array of checkboxes and a sumbit button, once button is clicked i go to another page where i handle those boxes checked the problem now is if NO checkboxes are checked and i hit the submit...i get errors on the other page my code: foreach($product_names as $product_row) { ?> <tr> <td > </td><td width='200px'><?php echo $product_row->getName(); ?></td> <td width='200px'><input type="checkbox" name="graphic[]" value="<?php echo $product_row->getId();?>" /></td> <td width='200px'><input type="checkbox" name="text[]" value="<?php echo $product_row->getId();?>" /></td> </tr> <?php } ?> </table> <table> <tr> <td> <input type='submit' name='submit' value='Submit'> <?php if ( (isset($graphic)) || (isset($text) )) { echo "checkboxes checked"; //show submit button } else { //hide submit botton and echo "no boxes check"; } ?> the above is NOT working please help????

Many thanks edited Hi i have made a login in system for a website iam trying to make. after you log in im trying to display the members username via the $_session created in the check_login.php. but when i Echo or print_r the $_session all is get is "welcome array" its like its not passing any information via the $_session from page to page. here is my code thanks in advance. Check_login.php session_start(); // username and password sent from form $myusername=$_POST['myusername']; $mypassword=md5($_POST["mypassword"]); // To protect MySQL injection (more detail about MySQL injection) $myusername = stripslashes($myusername); $mypassword = stripslashes($mypassword); $myusername = mysql_real_escape_string($myusername); $mypassword = mysql_real_escape_string($mypassword); $sql="SELECT * FROM $tbl_name WHERE username='$myusername' and password='$mypassword'"; $result=mysql_query($sql); // Mysql_num_row is counting table row $count=mysql_num_rows($result); // If result matched $myusername and $mypassword, table row must be 1 row if($count==1){ // Register $myusername, $mypassword and redirect to file "login_success.php" $_SESSION["myusername"]==$myusername; $_SESSION["mypassword"]; header("location:login_success.php"); } else { echo "Wrong Username or Password"; } ?> login_success.php <? session_start(); if($_SESSION['myusername']="$myusername"){ header("location:main_login.php"); } Echo "welcome" . $_SESSION['$myusername']; ?> thanks The $_Session has a url variable. Using a Dom how do I properly do: Code: [Select] html->load($_SESSION['variable']) I was thinking about breaking down the session to retrieve the value inside but I don't know how. For the last few hours I have been pulling my hair out on a session not storing when I moved from local host to my vps. I have been setting sessions like: $_SESSION['mydata'] = $variable; This works no problem on my wamp installation. However to get it to work on my vps, I have to store them like this $_SESSION[mydata] = $variable; Can someone please explain to me why this is the case? PHP 5.3.3 I am trying to redirect a user (currently logged in) to a page where they are able to edit a posted comment. To keep things secure I am using a forms hidden input value to pass the {postID} to a redirect page Code: [Select] <form name="post_edit" method="post" action="post-edit-redirect.php" > <input type="hidden" name="local" id="local" value="<?php echo $row_rsPosts['postID']; ?>" /> <input type="image" src="../imgs/managepost.png" name="submit" /> </form> On the redirect page (simplified below) I am setting the {postID} in a SESSION before redirecting to the user to the page to edit their post with the new $_SESSION val for {postID} set. Code: [Select] session_start(); $id = $_REQUEST['local']; $_SESSION['postID']=$id; header("Location: edit-post.php"); This is working fine in every browser except IE (some one please just put an end to it), where when the edit-post.php page is reached the $_SESSION['postID'] is empty. If I regenerate the session ID from the redirect page as below IE then sets the SESSION ok. Code: [Select] session_start(); session_regenerate_id(); $id = $_REQUEST['local']; $_SESSION['postID']=$id; header("Location: edit-post.php"); However there should be no need to do this and would rather not if there is no need. Any help on why IE is not setting the SESSION is appreciated, and I hope I am not covering old ground here however I am unable to find a solution anywhere. - Cheers Hey, i was reading some code and i find this: if(stristr($_SESSION["s"]["user"]["asdasd"]),$someString) How the double/triple [] in $_SESSION works ? PS: I tryied to google it but it was kinda hard to search :X Thanks. Just wanted to know if $_Session was a global thing or does php require cookies setup?
I assumed that I could do something like this:
PAGE: A.php
session_start();
$_Session['Cat'] = 'Meow';
// -----------------------
PAGE: B.php
if (isset($_Session['Cat']) && !empty($_Session['Cat'])){
echo $_Session['Cat'];
}
OUTPUT: Meow
// -----------------------
PAGE: C.php
if (isset($_Session['Cat']) && !empty($_Session['Cat'])){
echo $_Session['Cat'];
}
OUTPUT: Meow
I can't seem to get this to work.

Hello, I am currently making a small website that requires two languages. This is the class I made: Code: [Select] <?php class languages { public function __construct() { if(!isset($_SESSION['language'])) { $_SESSION['language'] = 'nl'; } $lang = isset($_GET['lang']) ? $_GET['lang'] : ""; $languages = array('en', 'nl'); if(in_array($lang, $languages)) { $_SESSION['language'] = $lang; } } } $languages = new languages; $language = $_SESSION['language']; ?> Now as soon I use index.php?lang=en, the website will display it self in English but, as soon I remove the &lang=en from the URI, the language gets not stored in the session and it displays nl agian.

It's still there, but SQL queries bomb, and var_dump returns: Warning: var_dump(): Property access is not allowed yet in C:\Program Files (x86)\Apache Software Foundation\Apache2.2\htdocs\voicereader\serverstate.php on line 595 Warning: var_dump(): Property access is not allowed yet in C:\Program Files (x86)\Apache Software Foundation\Apache2.2\htdocs\voicereader\serverstate.php on line 595 Warning: var_dump(): Couldn't fetch mysqli in C:\Program Files (x86)\Apache Software Foundation\Apache2.2\htdocs\voicereader\serverstate.php on line 595 Warning: var_dump(): Couldn't fetch mysqli in C:\Program Files (x86)\Apache Software Foundation\Apache2.2\htdocs\voicereader\serverstate.php on line 595 Warning: var_dump(): Couldn't fetch mysqli in C:\Program Files (x86)\Apache Software Foundation\Apache2.2\htdocs\voicereader\serverstate.php on line 595 Warning: var_dump(): Couldn't fetch mysqli in C:\Program Files (x86)\Apache Software Foundation\Apache2.2\htdocs\voicereader\serverstate.php on line 595 Warning: var_dump(): Couldn't fetch mysqli in C:\Program Files (x86)\Apache Software Foundation\Apache2.2\htdocs\voicereader\serverstate.php on line 595 Warning: var_dump(): Couldn't fetch mysqli in C:\Program Files (x86)\Apache Software Foundation\Apache2.2\htdocs\voicereader\serverstate.php on line 595 Warning: var_dump(): Couldn't fetch mysqli in C:\Program Files (x86)\Apache Software Foundation\Apache2.2\htdocs\voicereader\serverstate.php on line 595 Warning: var_dump(): Couldn't fetch mysqli in C:\Program Files (x86)\Apache Software Foundation\Apache2.2\htdocs\voicereader\serverstate.php on line 595 Warning: var_dump(): Couldn't fetch mysqli in C:\Program Files (x86)\Apache Software Foundation\Apache2.2\htdocs\voicereader\serverstate.php on line 595 Warning: var_dump(): Couldn't fetch mysqli in C:\Program Files (x86)\Apache Software Foundation\Apache2.2\htdocs\voicereader\serverstate.php on line 595 Warning: var_dump(): Couldn't fetch mysqli in C:\Program Files (x86)\Apache Software Foundation\Apache2.2\htdocs\voicereader\serverstate.php on line 595 Warning: var_dump(): Couldn't fetch mysqli in C:\Program Files (x86)\Apache Software Foundation\Apache2.2\htdocs\voicereader\serverstate.php on line 595 object(mysqli)#1 (17) { ["affected_rows"]=> NULL ["client_info"]=> NULL ["client_version"]=> int(50007) ["connect_errno"]=> int(0) ["connect_error"]=> NULL ["errno"]=> NULL ["error"]=> NULL ["field_count"]=> NULL ["host_info"]=> NULL ["info"]=> NULL ["insert_id"]=> NULL ["server_info"]=> NULL ["server_version"]=> NULL ["sqlstate"]=> NULL ["protocol_version"]=> NULL ["thread_id"]=> NULL ["warning_count"]=> NULL } There's got to be a way to save my SQL linkages so that I don't have to reconnect to the SQL database every time I want to see if new data has arrived, but this doesn't seem to be it. My PHP version is PHP 5.3.2.0. Thanks for any help. I have parts of my webpage protected with the following Code: [Select] session_start(); if(!isset($_SESSION['myusername'])){ header("Location:login.php"); } else { $username = $_SESSION['myusername']; } How secure is this? The goal is so people who don't have access to the page (don't have a login account) cannot get access Thanks for any tips |
