PHP - Proper Syntax With If Statements That Have No Else?

Ok this is puzzleing. I am geting "Could not delete data: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '1' at line 1". but its is deleting the entry that needs to be removed. The "1" is the entry. Just not sure what is causing the error. I do have another delete php but I have put that on the back burning for the time being.     <?php

         $con = mysqli_connect("localhost","user","password","part_inventory");
    // Check connection
if (mysqli_connect_errno()) {
  printf("Connect failed: %s\n", mysqli_connect_error());
    exit();
} else {
    
    $result = mysqli_query($con, "SELECT * FROM amp20 ");
    
    $amp20ptid = $_POST['amp20ptid'];                // escape variables for security
    $amp20ptid = mysqli_real_escape_string($con, $_POST['amp20ptid']);
    
    mysqli_query($con, "DELETE FROM amp20 WHERE amp20ptid = '$amp20ptid'");
      
    
if (!mysqli_query($con, $amp20ptid));

{
 die('Could not delete data: ' . mysqli_error($con));    
}
 echo "Part has been deleted to the database!!!\n";
    mysqli_close($con);
}
?>

Hi guys   I have this code below and all works fine when submitting this online application apart from when someone types either ' # & into one of the comment fields in which it throws up the error. Have tried various fixes from across the internet but no joy. Can anyone offer suggestions?   <?php $con = mysql_connect("localhost:3306","root","password"); if (!$con)   {   die('Could not connect: ' . mysql_error());   } mysql_select_db('sfapp', $con); $sql="INSERT INTO 'sfapp' ('surname_add','forename_add','dob_add','hometele_add','mobiletele_add','homeadd_add','siblings_add','schoolname_add','headname_add','schooladd_add','schooltele_add','schoolem_add','alevel_add','personstate_add','nameprovided_add','pe_add','se_add','PredGrade_Art','PredGrade_AScience','PredGrade_BusStudies','PredGrade_Electronics','PredGrade_EnglishLang','PredGrade_EnglishLit','PredGrade_French','PredGrade_German','PredGrade_Geog','PredGrade_Graphics','PredGrade_History','PredGrade_Maths','PredGrade_SepScience','PredGrade_ProductDesign','PredGrade_Spanish','PredGrade_Other','Gender_Male','Gender_Female','Sub_EnglishLit','Sub_Maths','Sub_FurtherMaths','Sub_Biology','Sub_Chemistry','Sub_Physics','Sub_French','Sub_German','Sub_Spanish','Sub_Geography','Sub_History','Sub_RE','Sub_FineArt','Sub_Business','Sub_Computing','Sub_GlobPersp','Sub_DramaAndTheatre','Sub_PE','Sub_Dance','Sub_Politics','Sub_Psychology','Sub_Sociology','readprospect_chk','Sib_Yes','Sib_No','Current_Student_Yes','Current_Student_No','I_Understand_chk','Current_Education_chk','Local_Care_chk','Staff_Cwhls_chk','Sub_Film')   VALUES ('$_POST[surname_add]','$_POST[forename_add]','$_POST[dob_add]','$_POST[hometele_add]','$_POST[mobiletele_add]','$_POST[homeadd_add]','$_POST[siblings_add]','$_POST[schoolname_add]','$_POST[headname_add]','$_POST[schooladd_add]','$_POST[schooltele_add]','$_POST[schoolem_add]','$_POST[alevel_add]','$_POST[personstate_add]','$_POST[nameprovided_add]','$_POST[pe_add]','$_POST[se_add]','$_POST[PredGrade_Art]','$_POST[PredGrade_AScience]','$_POST[PredGrade_BusStudies]','$_POST[PredGrade_Electronics]','$_POST[PredGrade_EnglishLang]','$_POST[PredGrade_EnglishLit]','$_POST[PredGrade_French]','$_POST[PredGrade_German]','$_POST[PredGrade_Geog]','$_POST[PredGrade_Graphics]','$_POST[PredGrade_History]','$_POST[PredGrade_Maths]','$_POST[PredGrade_SepScience]','$_POST[PredGrade_ProductDesign]','$_POST[PredGrade_Spanish]','$_POST[PredGrade_Other]','$_POST[Gender_Male]','$_POST[Gender_Female]','$_POST[Sub_EnglishLit]','$_POST[Sub_Maths]','$_POST[Sub_FurtherMaths]','$_POST[Sub_Biology]','$_POST[Sub_Chemistry]','$_POST[Sub_Physics]','$_POST[Sub_French]','$_POST[Sub_German]','$_POST[Sub_Spanish]','$_POST[Sub_Geography]','$_POST[Sub_History]','$_POST[Sub_RE]','$_POST[Sub_FineArt]','$_POST[Sub_Business]','$_POST[Sub_Computing]','$_POST[Sub_GlobPersp]','$_POST[Sub_DramaAndTheatre]','$_POST[Sub_PE]','$_POST[Sub_Dance]','$_POST[Sub_Politics]','$_POST[Sub_Psychology]','$_POST[Sub_Sociology]','$_POST[readprospect_chk]','$_POST[Sib_Yes]','$_POST[Sib_No]','$_POST[Current_Student_Yes]','$_POST[Current_Student_No]','$_POST[I_Understand_chk]','$_POST[Current_Education_chk]','$_POST[Local_Care_chk]','$_POST[Staff_Cwhls_chk]','$_POST[Sub_Film]')"; if (!mysql_query($sql,$con))   {   die('Error: ' . mysql_error());   }   ?> <?php //if "email" variable is filled out, send email   if (isset($_REQUEST['pe_add']))  {     //Email information     $admin_email = $_REQUEST['pe_add'];   $forename = $_REQUEST['forename_add'];   $email = "autoreply@testing.com";   $subject = "Application";   $desc =   "Dear $forename   Thank you for submitting your online application, we will be in touch shortly.

Say I have two areas of a website. 

1 - root directory (index, sign up, sign in)

2 - folders (this would contain folders such as snippets, members, assets)

Due to the nature of the folders, the links cannot be the same as they are on the pages in the root directory. Index page for example.  So if I'm on members/dashboard.php, any a links linking to index.php, will have to have "../" in front of them. To solve the issue, my current set up is like this. But I understand it's not the most efficient way to do this. I was wondering if you can share your expertise for a better method.

$currentPage = basename($_SERVER['PHP_SELF'], ".php");

<?php if($currentPage == 'index' || $currentPage == 'members') { ?>

Should this be the proper way of adding the getUsername() text in the query below:

Code: [Select]
mysql_query("UPDATE posts SET content = '$content', lastedit = ". getUsername() .":NOW() WHERE id = '$pid'") or die(mysql_error());

Im having trouble with this wondering if someone could help me out please

if (isset($_POST['escape'])) { || if (isset($_POST['suicide'])) {

its giving me a error on the ||

im writing it so that one or the other has to happend. is this the correct way to use this?

Hello everyone, I've recently asked a question about forms and Requinix mentioned PRG method of processing forms. The PRG idea solves my refresh and back button document expired problems but i notice something new: when i refresh a page or use the browser back button - then return to the PRG process - repeat a refresh or back button action - i notice that i can traverse the cache history as many times as my prg approach redirects me. I feel like i am not implementing this PRG method correctly, or is this correct?

Here is the form process if it helps solve the problem:

i have a login form which contains a CSRF token. when i submit the form i specify an action as /prg/ which submits the data to index.php in the prg folder. After processing the data, prg index.php redirects to the root (because you are logged in). One problem is that i have a logo on the login page that allows you to return to the root (localhost index page). When the form is not submitted or it contaiuns incorrect login data or the logo is clicked to return to homepage, then the history seems to repeat itself. I've read that people recommend to use a header 303 See Other but the result is the same. Basiclly, if i am implementing a prg correctly, then the question becomes how can i instruct a browser to ignore the redirect as if the cache contains only the index page?

i cannot find prg examples that involve a csrf token and other links on the protected page (prg/index.php protected because you need a form submission with a csrf token and it only processes data then redirects.) I don't see this happening in professional sites like Google or Microsoft etc. what am i doing wrong?

$sql = "SELECT option_id, id FROM bets WHERE win_status = '1' AND updated_at BETWEEN '$today 13:00:00.000000' AND '$tmrw 08:00:00.000000'";
$result = mysqli_query($connt, $sql);

foreach($result as $value)
{
	$value[] = arary_multisort();
	$oid = $value['option_id'];
	$gid = $value['id'];
     var_dump($value);
     //$gim = var_export($value);
}


foreach($result as $key => $value) {

	$info = array($value);

}
mysqli_close($connt);
$fl = array($oid, $gid);
print_r($fl);

array (
  'option_id' => 'game1a',
  'id' => '155670450',
)array (
  'option_id' => 'game2h',
  'id' => '386887537',

Either I can return 1 row and have the data sorted nicely or I can return an array but I can only seem to access the last array. Been stuck on this bit for atleast 2 hrs sadly. How can I rename the array? Some days I might have 100 results. Today we have two winners xP I really need to ctrl+z sublime cuz I tried what feels like everything. Ancy to move to the next part of this code MATH if you can kindly assist.

Yall have been extremely helpful in my last two posts 2/2 going on 3. Is there a place I can properly contribute lite silver :3

Code: [Select]
if (isset($select_category) || isset($most_liked)) {
// ALL but NO OTHER
if (((($select_category == 'All') || (!isset($select_category)))) && (!isset($most_liked))) {

           
$query = "SELECT * FROM con, user WHERE con.user_id = user.user_id ORDER BY contribution_date DESC";

fetch_all ($dbc, $query);


// CATEGORY but NOT most_liked
} elseif (isset($select_category) && !isset($most_liked)) {

$query = "SELECT * FROM con, user WHERE con.user_id = user.user_id AND category = '$select_category' ORDER BY contribution_date DESC";

fetch_all ($dbc, $query);

// CATEGORY and MOST_LIKED
} elseif (($select_category != 'All') && (isset($select_category) && isset($most_liked))) {

$query = "SELECT * FROM con, user WHERE con.user_id = user.user_id AND category = '$select_category' ORDER BY likes DESC";

fetch_all ($dbc, $query);

// ALL or NO CATEGORY but MOST LIKED
} elseif ((($select_category == 'All') || (!isset($select_category))) && (isset($most_liked))) {

$query = "SELECT * FROM con, user WHERE con.user_id = user.user_id ORDER BY likes DESC";
fetch_all ($dbc, $query);

}

}

What I am basically trying to accomplish is, choose a category through a drop down list, select that category and then go through all the rows in the database and print the content out.

As of now it is working for me, I am also using a pagination script to print out everything in a table.

The problem I am having is that fetch_all function is also printing the query out together with the content. Any ideas why it does that?

Did I use this function the right way?

If you need more information let me know.

Hi guys, 

I'm starting to get back into coding for a hobby and wondering is there a better way of doing these php and mysql calls? they all work but not sure if it was the efficent way or is there others that everyone else uses?

 

//connection for user details lookup
$sql0 = "SELECT uid, fullname, emailaddress, created_at FROM MK_users WHERE uid={$_SESSION['id']}";
$result0 = $conn->query($sql0);

//connection for user against role acceess
$sql2 = "SELECT role_uid, role_bid, role_access, access_created_at FROM MK_role_access WHERE role_uid={$_SESSION['id']}";
$result2 = $conn->query($sql2);

 while($row2 = $result2->fetch_assoc()) {
    $_SESSION['role_bid'] = $row2["role_bid"];
  }

//connection for role access against business lookup
$sql3 = "SELECT businessname, account_type, website, main_address, logo FROM MK_baccounts WHERE bid={$_SESSION['role_bid']}";
$result3 = $conn->query($sql3);

while($row3 = $result3->fetch_assoc()) {
  
    $_SESSION['businessname'] = $row3["businessname"];
  }
 

Hi Guys, 

Total PHP Noob here. I’ve run into a brick-wall and would appreciate some words of wisdom. 
I am working on a fairly complicated (at least to my skill level..)  home automation/IOT -project and unexpectedly have a big problem establishing a connection between the Internet and my home network. I’ve spent too many hours trying to solve this and eventually have reverted to a super basic Hello World -example to highlight the issue.

I can do this with a browser:

http://86.60.161.24  // will echo hello World

I can’t do this with my server:

<?php
  $url = 'http://86.60.161.24';
  $contents = file_get_contents($url);
  echo ($contents);
?>

It looks like the server-side HTTP -request never “touches” my Arduino-chip. No network activity detected. Obviously there is going to be a lot more data transfer happening but I need to solve this issue first. 

Is there anything I can do to make this work? Any and all input greatly appreciated. Cheers!!

 

Hi..

I create mysql syntax for query testing before i input to my php code

here is my mysql code:

Code: [Select]
set @t = 0;
set @rqty=31968;
SELECT LOT_CODE as code,  DATE_ENTRY,   
CASE WHEN @t+OUTPUT_QTY > @rqty
THEN @rqty  -@t 
ELSE OUTPUT_QTY
END as qty,
@t := @t + d.OUTPUT_QTY as cumulative   
FROM dipping d  WHERE SUBSTR(LOT_CODE, 9,4) = 'P28' AND (@t < @rqty);

and i attach the sample output of the above query.

Now that query test is work i  will input that code to my php codes.


     $sql = "SELECT SKUCode, Materials, Comp, Qty 
     FROM bom  WHERE SKUCode = '$SKUCode'";
     $res = mysql_query($sql, $con);

    ($row = mysql_fetch_assoc($res));
     $Materials = $row['Materials'];
     $Qty = $row['Qty'];
     $Comp = $row['Comp']; //P28
//-----Compute Req Qty and Save to table---//     

     $ReqQty = $Qty * $POReq; // 31968


     
$sql = "UPDATE bom SET ReqQty = '$ReqQty' WHERE SKUCode = '$SKUCode' AND Materials = '$Materials'";
$resReqQty = mysql_query($sql, $con);

$t = 0;

$sql = "SELECT LOT_CODE as code,  DATE_ENTRY,   
CASE WHEN $t+OUTPUT_QTY > $ReqQty 
THEN $ReqQty  -$t  
ELSE OUTPUT_QTY 
END as qty,
$t := $t + d.OUTPUT_QTY as cumulative   
FROM dipping d  WHERE SUBSTR(LOT_CODE, 9,4) = '$Comp' AND ($t < $ReqQty)";



when I echo the query:

I got this:

 SELECT LOT_CODE as code, DATE_ENTRY, CASE WHEN 0+OUTPUT_QTY > 31968 THEN 31968 -0 ELSE OUTPUT_QTY END as qty, 0 := 0 + d.OUTPUT_QTY as cumulative FROM dipping d WHERE SUBSTR(LOT_CODE, 9,4) = 'P28' AND (0 < 31968)

then I run it to the sql

and I got an error:

Error Code : 1064
You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ':= 0 + d.OUTPUT_QTY as cumulative FROM dipping d WHERE SUBSTR(LOT_CODE, 9,4) = '' at line 1

Any help is highly appreciated

Thank you so much

Hi,
I'm pretty new to php and need a bit of basic help.

I have a header and footer include file in a "views" folder. The header itself has a function that's included from another directory. Now when I try to include the header in by index.php in the root it throws and error saying it can't find my function include. Obviously the include directory is relative to the file it's included in. So, what's the trick to fixing this problem? And what's the lesson for future projects? Thanx in advance.

Hi All,

Can any body let me know what is proper way to write below code?

while($row = mysql_fetch_array($result))
{
   for ($colq=0; $colq<=$col_no;$colq++)
    {    
      while($col = mysql_fetch_array($result_display_sequences))
          {
            for ($b=0; $b<=$seq_num;$b++)
              {
              echo $col[$b] . " ";
                   while($asso = mysql_fetch_array($result_column_associated))
                   {
                         for ($c=0; $c<=$asso_num;$c++)
                            {   
                       echo $asso[$c] . " ";
                         if ($col[$b] == $asso[$c])
                               {         
                                 echo "<td>" . $row[$colq] . "</td>";
                               }
                            }
                   }
               }

I am using a MVC framework and in my controller I have defined a class variable for configurations.  In my action I have a call to the configuration class to set the class variable to the current configurations.

Code: [Select]
public $configArray = array();

public function actionBuild($id)
{
$this->configArray=Config::model()->getConfigArray($id);

$this->buildStep1();
...
}




When I echo the configuration in the method it is 10 but when I echo in buildStep1 it is 11.  What is the proper way for configArray to be global and updated when I call getConfigArray for use in functions in the class?
