PHP - Can Not Get $_post, Even Though I Can Print_r It
Here's the result of my problem:
Array ( [nav_create_title] => hel [nav_visible] => 1 [category_position] => 4 ) ( ! ) Notice: Undefined index: category_postion in C:\wamp\www\tryitandbuyit\includes\category_create_process.php on line 7 Call Stack # Time Memory Function Location 1 0.0010 370336 {main}( ) ..\category_create_process.php:0 Here's how I'm trying to assign and echo $_post. print_r($_POST); $category_pos = $_POST["category_postion"]; $nav_title=$_POST["nav_create_title"]; $nav_visible=$_POST["nav_visible"]; echo $nav_title; echo $category_pos; echo $nav_visible; As you can see, it prints the correct value and name from the array... why the heck can't I assign or echo it? Here is how I am sending it from the other page in a form (it used to be simple, but I've been trying every work around i can think of: <?php $result=mysql_query("SELECT * FROM category WHERE visible='1' ORDER BY position ASC"); $row=mysql_fetch_array($result); $positionID=$row['position']; $position=$row['position']; $selectname= "Select A Position:<br />"; $selectname .= "<select name="; $selectname .= "'category_position'"; $selectname .= ">"; echo $selectname; $rownumber=mysql_num_rows($result); $rownumber_temp=$rownumber+1; For($i=1; $i<=$rownumber_temp; $i++) { echo "<option value= $i>" . $i . "</option></br>"; } $selectname2 = "echo \"<br />\""; $selectname2 .= "echo \"<br />\""; $selectname2 .= "echo \"</select>"; echo $selectname2; Similar TutorialsI've got a few hours in this, read the manual on return (and it appears my print_r should be working!).. And I am unable to get print_r() to output the contents of my function array. What am I doing wrong? function getStateName() { $stateName = array("Alabama","Florida","Nevada"); return $stateName; } echo "<pre>"; echo print_r($stateName); echo "</pre>"; <?php error_reporting(0); $numm0 = array(1,2,3,4,5,6); $numm1 = array(1,3,4,5,6); $numm2 = array(1,2,3,4,6); $numm3 = array(1,2,3,5,6); for($i = 0;$i < 4;$i++) { print_r($numm.$i); } for($i = 0;$i < 4;$i++) { $w.$i = array_sum($numm.$i); print_r($w.$i); echo "<br>"; } ?> this code just hangs when executed. how can the syntax of the print_r() function and array_sum() function be modified? need help... I am working on modifying some code and wanted to check some variables, but am stuck on something that is probably simple, just over my head. If I do the following: print_r ($this); I get this result (I used PRE tags to format it) ViewList Object ( [_name] => list [_models] => Array ( => ModelList Object ( [_data] => Array ( => stdClass Object ( [id] => 70 [catid] => 1 etc...... Moving down, I typed this... print_r ($this->_models); and get this... Array ( => ModelList Object ( [_data] => Array ( => stdClass Object ( [id] => 70 [catid] => 1 How would I get, for instance, the id? If I try print_r($this->_models->list); nothing happens. In other words, if I wanted to return the id, what would it be -- $this->_models->??? . I tried all kinds of combination's and other ways to do it, just can't figure it out. I know it is my limited knowledge with PHP , so could someone point me in the right direction. Thanks, Doc [/list][/list] Hey Is there a way to trim the print_r($array); so its completed and void of white space? It prints like this: Code: [Select] Array ( [0] => Array ( [id] => 10 [f] => data/tiles/image.png ) ) But I want it to be compressed like this: Code: [Select] Array([0]=>Array([id]=>10[f]=>data/tiles/image.png)) This is then to be stored in the database, so any compressed possible is a plus in this situation. Any ideas? After switching from PHP 5.3 on Windows Server 2003 to PHP 7.4.3 on Linux Mint 19.3 (Tricia Cinnamon), I find that the output of print_r() has changed. If we look at the documentation (https://www.php.net/manual/en/function.print-r.php), the provided example output is as it was on my earlier machine:
<pre>
Array
(
[a] => apple
[b] => banana
[c] => Array
(
[0] => x
[1] => y
[2] => z
)
)
</pre>
However, on the second machine, the output is:
<pre>
Array
(
[a] => apple
[b] => banana
[c] => Array
(
[0] => x
[1] => y
[2] => z
)
<blank line>
)
</pre>
Note the unexpected new line after each recursed array's closing parenthesis. The new line is not present after the outermost array closing parenthesis. Also to note, there is a newer version of XDebug installed. My question is: Is this a bug? (Follow-on question: if possible to determine at which version the output changed, what version would that be?) This difference is causing existing code to not be able to correctly parse that output. Hey guys it's been a long time, but I am back with php! Anyway here's my dilemma: test.php <?php <?php $name = array('Chris', 'Bob', 'Jack'); $names = print_r($name); ?> Simple enough right? Well although I am not printing/echoing these results to screen it does it automatically. Meaning when I point my browser to test.php it outputs this: Code: [Select] Array ( [0] => Chris [1] => Bob [2] => Jack ) Rather than only assigning the value to the $names variable, which is what I would expect it to do. Is this normal behaviour or is there something I can change on php.ini? Thank you! i have checkboxes on the database page and if checked they send to the shopping basket i have the items selected to display but like this
Array ( [0] => Imagine DragonsImagine DragonsRockI Bet My LifeKIDinaKORNER1.25Brand new single from the incredible Imagine Dragons )
So I have been printing out some debug information, and now I am trying to instead save it to a string, which I will print out at the end of the page. Here is some specific problematic code: $myplugin_debug_test.= "\n[GETTING COOKIES...\n"; $myplugin_debug_test.= print_r($myplugin_all_cookies);//THIS IS LINE 38 $myplugin_debug_test.= "\n... DONE]<br/>\n"; However, when I do this I get the following error: Quote Warning: Cannot modify header information - headers already sent by (output started at ...:38 So my question is how can I output the array data into a string, so that I can print it out later. Like what am I doing wrong? Is there a better way to do this? Thanks! the array is getting the values as he should get and from there i send them to $temp (string),but when i'm trying to print them i can't. the array and the string at the end of code saved the values that the code gave them,but i can print the values one by one, but i need the values in string and the array at the end and print $temp(string) in a row without white space. print_r is working but she's not build to this job can someone look at the code and the result of the code and tell me what seem to be the problem and how to fix that? the problem start with $txt when the array is getting the values. the output of this code:http://pastebin.com/0QkzjviW the code page is attach to this message as php file. Hi guys, running through this tutorial at the moment: http://www.tizag.com/phpT/forms.php I seem to keep having problems with the $_POST variable. Is that obsolete syntax now? Here's the part I get an error on: <html> <body> <?php $quantity=$_POST['quantity']; $item=$_POST['item']; echo "You ordered".$quantity."".$item.".<br/>."; echo "Thank you for ordering from Boombaby art supppplies!"; ?> </body> </html> Here's the error: ( ! ) Notice: Undefined index: quantity in C:\wamp\www\process.php on line 4 Call Stack # Time Memory Function Location 1 0.0009 363936 {main}( ) ..\process.php:0 ( ! ) Notice: Undefined index: item in C:\wamp\www\process.php on line 5 Call Stack # Time Memory Function Location 1 0.0009 363936 {main}( ) ..\process.php:0 You ordered. .Thank you for ordering from Boombaby art supppplies! Any help would be appreciated. I tried googling but everything didn't seem to answer my question or was too confusing. Thanks. I use a form to sent date and use php to display it . However , the code only can working on one page. I can not turn the page. I do not why . Please tell me reason .

Thank you, Brian Hi guys, I have a form using radio buttons. For the radio button, lets just say i have the id name as 'rim' + number eg; rim0, rim1, rim2.... When i post the data to another file to execute the data collected, naturally i would use the: Code: [Select] $rim0=$_POST['rim0']; $rim1=$_POST['rim1']; .... $rim10=$_POST['rim10']; i tried to shorten this process using this method: Code: [Select] //$q is part of the post variable. for($x = 0; $x < count($q); $x++){ $rim[]=$_POST['"rim"."$x"']; } But i get this error Code: [Select] Notice: Undefined index: "rim"."$x" in D:\Apache Software Foundation\Apache2.2\htdocs\.....\#####.php on line 20 Notice: Undefined index: "rim"."$x" in D:\Apache Software Foundation\Apache2.2\htdocs\.....\#####.php on line 20 Notice: Undefined index: "rim"."$x" in D:\Apache Software Foundation\Apache2.2\htdocs\.....\#####.php on line 20 Notice: Undefined index: "rim"."$x" in D:\Apache Software Foundation\Apache2.2\htdocs\.....\#####.php on line 20 Notice: Undefined index: "rim"."$x" in D:\Apache Software Foundation\Apache2.2\htdocs\.....\#####.php on line 20 Notice: Undefined index: "rim"."$x" in D:\Apache Software Foundation\Apache2.2\htdocs\.....\#####.php on line 20 Notice: Undefined index: "rim"."$x" in D:\Apache Software Foundation\Apache2.2\htdocs\.....\#####.php on line 20 Notice: Undefined index: "rim"."$x" in D:\Apache Software Foundation\Apache2.2\htdocs\.....\#####.php on line 20 Notice: Undefined index: "rim"."$x" in D:\Apache Software Foundation\Apache2.2\htdocs\.....\#####.php on line 20 Notice: Undefined index: "rim"."$x" in D:\Apache Software Foundation\Apache2.2\htdocs\.....\#####.php on line 20 Is there something wrong with my POST syntax? ok am workin on this script its a points market for a text based game but my money is not taking the amount of the players i points on the market ... just say i post 10 points for $29.000.000 ... and when the player buys the points it takes the money from that user and give the user points but .... when the user buy the points it dont give the user the money it give $290 ?? not sure is its my SQL av post that to Code: [Select] <?php include 'header.php'; $_POST['buypoints'] = abs(intval($_POST['buypoints']));{ $result = mysql_query("SELECT * FROM `pointsmarket` WHERE `id`='".$_POST['points_id']."'"); $worked = mysql_fetch_array($result); $price = $worked['price']; $amount = $worked['amount']; $totalcost = $price * prettynum($_POST['amount']); $newpointsinmarket = $amount - prettynum($_POST['amount']); $user_points = new User($worked['owner']); if ($worked['owner'] == $user_class->id) { echo Message("You have taken ".$_POST['amount']." points off the market."); $newpoints = $user_class->points + $_POST['amount'];; $result = mysql_query("UPDATE `grpgusers` SET `points` = '".$newpoints."'

I need your help.. I'm having a problem in getting the post values from my form, I have 2 arrays and some values: Code: [Select] $total = 3; $array1 = (branch1, branch2, branch3); $array2 = (100, 200, 300); $count = count($array1) - $total; then i combine them Code: [Select] $array3 = combine_array($array1, $array2); if $count is 0, using a foreach loop i echo each value and key Code: [Select] foreach($combined_array as $value => $key) { echo "<tr>"; echo "<td><input type='hidden' name='branch' value='{$value}'></td>"; echo "<td id='edit'>" . "<input type='submit' name='edit' value='' />" . "</td>"; echo "<td id='sep'> / </td>"; echo "<td><input type='hidden' name='id' value='{$key}'></td>"; echo "<td id='del'>" . "<input type='submit' name='delete' value='' />" . "</td>"; very simple and it works perfectly fine, but if the variable $count is not equal to 0, i append both arrays(1 & 2) so that it will be equal to 0. (data appended is not important i just need them for the table output.) Code: [Select] for($i = 0; $i < $count; $i++) { $array1[] = "null" . $i; $array2[] = $i; } // then combine $array3 = combine_array($array1, $array2); // echo each value and key foreach($combined_array as $value => $key) { echo "<tr>"; echo "<td><input type='hidden' name='branch' value='{$value}'></td>"; echo "<td id='edit'>" . "<input type='submit' name='edit' value='' />" . "</td>"; echo "<td id='sep'> / </td>"; echo "<td><input type='hidden' name='id' value='{$key}'></td>"; echo "<td id='del'>" . "<input type='submit' name='delete' value='' />" . "</td>"; echo "</tr>"; i tried to view the code souce and both hidden fields contain correct data but if i tried to delete/edit it doesn't work. i tried echoing/print_r the $_POST['branch'] & $_POST['id'] after i click on delete/edit and it always gives me the last $value and $key of the combined array for all the submit buttons.. Any thoughts? As i said the appended data is not important but the problem is once i click delete the original values in array1 and 2 are not what post is giving me..therefore i cannot delete or edit them.. Sorry if my post is too long.. Thanks in advance! I'm have a form with at least 3 fields(name, price, and date). I have some jquery that produces another date form input every time a certain link is clicked so there can be several date inputs. The first one(not dynamically created) has the form name "date_1". All the jquery produced inputs have the name "in_123435443453". The number after "in_" is the current timestamp. I'm trying to cycle through only the POSTs that start with "in_" and take their value to insert into database. I can't figure out how to grab the date("in_25346435253") POST in the foreach loop though because they're all unique. I'm using the codeigniter framework. That's why the code to insert into the db make look weird. Code: [Select] <?php foreach($this->input->post() as $key => $value) { $start = substr($key, 0, 3); if($start == "in_") { $cal_id = $this->input->post('cal_id'); $exc_name = $this->input->post('exc_name'); $date = $this->input->post('???'); // <-- part i need help with $price = $this->input->post('price'); $date = date("Y-m-d 00:00:00",strtotime($date)); $data = array( 'cal_id' =>$cal_id, 'name' => $exc_name, 'date' => $date, 'price' => $price ); $this->db->insert('Exceptions', $data); } } ?> Hello,
I am quite new to the php and website scene and i am trying to find the best way to validate and sterilize my $_post the way i have come up with is
$id = filter_var(mysql_real_escape_string($_POST['id']),FILTER_SANITIZE_NUMBER_INT);or $id = mysql_real_escape_string($_POST['id']); $id1 = filter_var($id,FILTER_SANITIZE_NUMBER_INT);which will be the best way to do it or is there a better way. Thanks Edited by AdamHull12, 04 October 2014 - 11:15 AM. |
