PHP - Removing A $_session Entity If Values = X
Is there a way to make it
How can I go about removing a $_SESSION entity if certain array values of it equal a specific value? I am thinking something along the lines of this:
if (isset($_SESSION['cart']['content'][$_POST['id']])) = array ('sizes' => 0, 'sizem' => 0, 'sizel' => 0, 'sizexl' => 0) { // remove $_SESSION['cart']['content'][$_POST['id']] } Similar Tutorials
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. I am trying to create a history of requested URI's (upto 3) for two purposes Login page and Error Logging. My problem is the Session is written and the values are set yet i can not retrieve the values in it upon a refresh. The use of an Array is to manage the quantity of max values (not written in yet).
<?phpSession contains
REQUEST_URI|a:1:{i:0;s:19:"1422925783,/~Debug/";}
After a refresh i expect
REQUEST_URI|a:2:{i:0;s:19:"1422925783,/~Debug/";i:1;s:28:"1422925784,/~Debug/index.php";}
Yet it only contains
REQUEST_URI|a:1:{i:0;s:28:"1422925784,/~Debug/index.php";}

Any help please
Thanks 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>
I am using API-Platform, Doctrine, and Symfony with entities that utilize class type inheritance to extend an abstract entity. I've been running into one issue after another primarily related to the serialization process (serialization groups, parent annotations not propagated to the child, etc), and while I am sure user error on my part is part of the culprit, it appears that API-Platform and potentially Symfony and Doctrine don't fully support entity inheritance. My reason for thinking so is the incredibly sparse amount of documentation on the subject and remarks on quite a few github issues posts and other blogs how it is "bad practice". For instance, say I have Mouse, Cat, and Dog which all extend AbstractAnimal, and each has a bunch of common properties such as birthday, weight, etc, and methods such as eats(), sleeps(), etc. Sorry in advance for using hypothetical entities but I don't think doing so distracts. I like how inheritance allows me to keep all common properties in a single table, but can let that go. More importantly, the subset mouse, cat, and dog table shares an ID from the animal table allowing me to associate all animals to some other table (i.e. many-to-one to person whether they are their pet or many-to-many to country whether they are native to a country), and to retrieve a list of animals and filter by some property or type as needed without a bunch of unions. To me, this sounds like inheritance, but if the products I am using don't support it very well, it doesn't matter. First question. Is entity inheritance considered bad practice? And even if not, is it common for frameworks to limit their level of support for them? If so, what can I do about it? Maybe favor composition over inheritance? Okay, great, I now have a single animal table which makes all my SQL concerns issues go away and I am pretty confident that my serialization issues will also go away. All I need to do is inject each animal with some "thing" to make them a mouse, cat, or dog. But what do I call this thing? I've struggled with this topic for a while and asked the same question regarding how to deal with BarCharts, PieCharts, GaugeCharts, LineCharts, etc all being charts but all acting slightly differently, and never really came to any conclusion. For a non-hypothetical scenario, I have BacnetGateway and ModbusGateway which extend AbstractGateway. Okay, this one is easy and I change to just having a Gateway and inject either BacnetProtocol or ModbusProtocol. For another non-hypothetical scenario, I have PhysicalPoint which represents some real environmental parameter, VirtualPoint which represents combining one or more PhysicalPoints or VirtualPoints, and TransformedPoint (feel free to provide a better name) which represents performing some time function such as integrating over a given time. Currently, they all extend AbstractPoint, but if I was trying to do so with composition, I could inject PointType but don't think doing so makes sense. For my hypothetical scenario, do I make a DNA interface and inject an Animal with DogDNA to get a dog? I really need to get my head around this once and for all. Thanks I can create a one-to-one relationship between two tables by placing a unique constraint on the foreign key and making it NOT NULL, and make it one-to-at-most-one by removing the NOT NULL constraint. My question is what criteria should one use to determine which table holds the foreign key? For instance, I have the Car and Motor entities as shown below where one Car has one Motor, and conversely one Motor is used by one Car.
AbstractPart
Car extends AbstractPart What reasoning should one use to determine whether the Car table contain the Motor ID or should the Motor table contain the Car ID? I am using PHP and Doctrine to store and manipulate Highchart objects such as the following:
{
"chart": {
"type": "bar"
},
"xAxis": {
"categories": ["Africa", "America", "Asia", "Europe", "Oceania"]
}
},
"series": [{
"name": "Year 1800",
"data": [107, 31, 635, 203, 2]
}, {
"name": "Year 1900",
"data": [133, 156, 947, 408, 6]
}, {
"name": "Year 2000",
"data": [814, 841, 3714, 727, 31]
}, {
"name": "Year 2016",
"data": [1216, 1001, 4436, 738, 40]
}]
}
My DB schema is: BarChart -id (PK) -name (string) BarChartSerie -id (PK) -barChartId (FK) -name (string) -position (int) BarChartCategory -id (PK) -barChartId (FK) -name (string) -position (int) BarChartNode -barChartSerie (FK) -barChartCategory (FK) -value (decimal) The chart entity has a collection of serie and category, and the serie and category entities both contain a reference to the shared node. I wish to clone the chart entity and thus use __clone() to set the chart, category, and serie entity's' PK to NULL, however, am running into issues as the node entity still has the original entitiy's PKs. I think maybe I should be creating the entities differently. Any suggestions how these objects should be created? Maybe instead have my series contain a collection of nodes and have each of these nodes contain a reference to the applicable category? Thanks Hello I am working on my graduation project and I have a critical problem with my php code and I am just beginner in php coding. I am reading from text file IDs of papers and want to link between the ID that I read form my text file and the XML file so that is my code : <?php $file = fopen("abstract/Temp_id.txt","r"); $ids; while(!feof($file)) { $ids = fgets($file); $xml = simplexml_load_file("abstract/$ids");//abstract is the folder which I save my files and //read from it $title="bibliomisc =".$xml->articleinfo[0]->bibliomisc; echo $title; echo"<a href=abstract/$ids title='Click to open '>$ids</a>"; } fclose($file); ?> BUT I worked on openssl and it is working if I give it the name of ID e.g. $xml = simplexml_load_file("abstract/8104317");//it is working but if I read from file I got that error Warning: simplexml_load_file() [function.simplexml-load-file]: I/O warning : failed to load external entity "8104317.xml " in /opt/lampp/htdocs/GP/xml_test.php on line 9 Notice: Trying to get property of non-object in /opt/lampp/htdocs/GP/xml_test.php on line 12 Notice: Trying to get property of non-object in /opt/lampp/htdocs/GP/xml_test.php on line 12 bibliomisc = 8104317.xml Warning: simplexml_load_file() [function.simplexml-load-file]: I/O warning : failed to load external entity "" in /opt/lampp/htdocs/GP/xml_test.php on line 9 Notice: Trying to get property of non-object in /opt/lampp/htdocs/GP/xml_test.php on line 12 Notice: Trying to get property of non-object in /opt/lampp/htdocs/GP/xml_test.php on line 12 bibliomisc = help please thanks I am a little experienced with PHP sessions, but not totally as I haven't got my head completely around its logic yet, as your about to see. I wonder wondering how I can go about adding a session entity from a HTML form input? I'm guessing it will be something like: $_POST['name'] => $_SESSION['delivery']['name']; Then, to echo the session entity, you would simply do something like: echo $_SESSION['delivery']['name']; ? I have: {$content['size']} inside Code: [Select] echo ""; I had to switch the quotes around because I added something else that required me to do so, so it now sits at this: {$content["size"]} inside Code: [Select] echo ''; Before I made the quote switch, it was echoing "Large", which is correct. Now after the switch, it echo's "{$content["id"]} ". Why?! I've tried 567568758654 different combinations of quotes and removing {} and stuff but non of them fix it. I don't even see why its suddenly not even echoing! All I did was quote reverse! I was looking over some code that someone else had written when I noticed a line with "$this->entity" in it. "Entity" is recognized as PHP syntax in my text editor but I cannot find any reference to it in any documentation that I've looked through. Where can I find more information about the "entity" class? Thanks in advanced! 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 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. edited 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 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. Can somebody help me? Thank you! Hi i'm new to the forum and i'm wondering if anyone here could help me out with the problem i'm having. the script i have uses $_SESSION['userid'] = $users['id']; and i'm not exactly sure how to read that .. any information would be helpful. thanks in advance I have parts of my webpage protected with the following Code: [Select] session_start(); if(!isset($_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 |
