PHP - Insert Multiple Rows Not Work.

Hello all,

   I am trying to learn OOP in PHP so please forgive my ignorance. I seem to be having difficulty inserting data into my database from checkbox items. My database has a column for each each fruit. I would like for each column to be populated with either a one(1) for checked or a zero(0)  for not checked. Currently, my attempts have failed. I can either get all checkboxes to insert all zeros or I can get the first column to insert a one(1) while the others as zeros. Is there anybody here that can help me figure out what I am doing wrong and help me to re-work my code so I can get this to work? If anybody can help me using OOP methods that would be fantastic. Thank you all in advance.

 

$preffruit->create_preffruit(array(

  'fruit_apple' => escape(Input::get(['fruit_selection'][0]) ? 1 : 0),
  'fruit_orange' => escape(Input::get(['fruit_selection'][1]) ? 1 : 0),
  'fruit_banana' => escape(Input::get(['fruit_selection'][2]) ? 1 : 0),
  'fruit_pear' => escape(Input::get(['fruit_selection'][3]) ? 1 : 0),
  'fruit_kiwi' => escape(Input::get(['fruit_selection'][4]) ? 1 : 0)

  ));

<input type="checkbox" name="fruit_selection[]" value="fruit_apple">
<input type="checkbox" name="fruit_selection[]" value="fruit_orange">
<input type="checkbox" name="fruit_selection[]" value="fruit_banana">
<input type="checkbox" name="fruit_selection[]" value="fruit_pear">
<input type="checkbox" name="fruit_selection[]" value="fruit_kiwi">



public function insert_preffruit($table, $fields = array()) {
			
			$keys = array_keys($fields);
			$values = '';
			$x = 1;			
			
			foreach($fields as $field) {
				$values .= '?';
				if($x < count($fields)) {
					$values .= ', ';
				}
				$x++;
			}		
				
				$sql = "INSERT INTO preffruit (`user_id`, `" . implode('`, `', $keys) . "`) VALUES (LAST_INSERT_ID(), {$values})";		
			
			if(!$this->query($sql, $fields)->error()) {
				return true;
			}			
			
			return false;
		}

Hi all,

I am managing a social network and am creating a script to allow the admin to private message all users on the site. Even setting the max execution time to unlimited within the file does not allow us to insert all 40,000 rows into the 'message' table, it stops after several thousand rows. Our hosts tell us setting this globally is a bad idea/unstable.

Does anyone have some advice on the best to do this? No email notifications need to be sent so it is purely allowing the script to run it's full course without stopping. I did consider a cron job but without emails doing in 'batches' seems a bit unecessary so I'm clearly missing something. ANy and all advice would be most welcome!

Hello, is it possible to insert somehow information from textarea to mysql?
For example i have 3 lines in text area:
John Tacker is a bad guy
Tom Tacker has a big nose
Ted Tacker is the same person as John Tacker
and i want to insert them in table's different rows

Hi, I have an app that access a MySQL database via a php script.
I noticed that INSERT was returning error but the data was being recorded successfully.
I finally traced the problem to be related with the line 
echo $conn->affected_rows;   

For some reason when it is an SQL INSERT it returns -11 but as I said the INSERTS executes successfully.

The app requesting the service sends in sequence:

char* txtSQL[]={"INSERT INTO activity (mac,jd,date,time,area,type,value) VALUES ('a9c4952de6b4',2458454,'2018-12-01','10:22','Area0002','h',130)",
                            "INSERT INTO activity (mac,jd,date,time,area,type,value) VALUES ('a9c4952de6b4',2458454,'2018-12-01','10:22','Area0002','h',130)",
                            "INSERT INTO activity (mac,jd,date,time,area,type,value) VALUES ('a9c4952de6b4',2458454,'2018-12-01','10:22','Area0002','h',130)",
                            "INSERT INTO activity (mac,jd,date,time,area,type,value) VALUES ('a9c4952de6b4',2458454,'2018-12-01','10:22','Area0002','h',130)",
                            "UPDATE activity set value=333 where value=130",
                            "SELECT sum(value) from activity where mac='a9c4952de6b4'",
                            "DELETE from activity WHERE value=333"};

I set a monitor to check what was being returned and got:

query=INSERT INTO activity (mac,jd,date,time,area,type,value) VALUES ('a9c4952de6b4',2458454,'2018-12-01','10:22','Area0002','h',130)

HttpResponse:  -   httpResponseCode: -11
query=UPDATE activity set value=333 where value=130

HttpResponse: 1379 *   httpResponseCode: 200

Any help will be much appreciated.

So when I execute this it'll go for about 130k rows then give a 500 error. Any ideas how to avoid this and get it to complete?

Code: [Select]
$i=10000000;
while($i<=99999999)
  {
  $public = $i;
  $value = rand(10000000, 99999999); 
  mysql_query("INSERT INTO yummy_table (public, value) VALUES('$public', '$value' ) ") or die(mysql_error()); 
  $i++;
  }
echo "done";

I have a form where a user can duplicate part of a form like below:

{
echo "qty " . clean($system_controllers_qty[$i]) . "<br/>";
echo "make " . clean($system_controllers_make[$i]) . "<br/>";

This just outputs all the fields I post at the moment. Say I have 3 different disk types, it's going to loop 3 times. Is it possible to make this all into 1 giant query or am I better off doing each query separately? Each section is a different table.

Hi again all,

Why does the foreach loop im doing, put the array values from collection, into seperate table rows rather than 1 row per whole array?



    <?php
        class registration{                    
            public $fields = array("username", "email", "password");
            public $data = array();
            public $table = "users";
            public $dateTime = "";
            public $datePos = 0;
            public $dateEntryName = "date";
            public $connection;
            
            function timeStamp(){
                return($this->dateTime = date("Y-m-d H:i:s"));
            }
            
            function insertRow($collection){      
                    //HERE
                    foreach($this->fields as $row => $value){
                        mysql_query("INSERT INTO $this->table ($value)
                        VALUES ('$collection[$row]')");
                    }
                    
                    mysql_close($this->connection->connectData);
            }
            
            function validateFields(){            

                $this->connection = new connection();
                $this->connection->connect(); 
                        
                foreach($this->fields as $key => $value){
                    array_push($this->data, $_POST[$this->fields[$key]]);
                }
                $this->dateTime = $this->timeStamp();
                array_unshift($this->data, $this->dateTime);                
                array_unshift($this->fields, $this->dateEntryName);   
                
                foreach($this->data as $value){
                    echo "$value";
                }
                
                $this->insertRow($this->data);
            }
        }
        
        $registration = new registration();
        $registration->validateFields();
    ?>




I end up with 3 rows

row 1: username
row 2: email
row 3 : password

rather than row 1:username email password.

Hey All,

I tried seraching, but I'm not sure what exactly to search for. Here's what I need to do, and any push in the right direction would be great:

I have a PHP form, with the Following:

Text Box: Student ID
Checkboxes for Activities

What I need to do is somehow loop through and make a new row for each activity. Example, if I entered Student ID 105 and Activities are Basketball, Baseball, and Chess Team, I need three different rows in the database each listing the individual activity and the student ID.

Any suggestions? I know how to do this if it was one entry (radio buttons) but want to be able to enter multiple rows at a time. Thanks!

I want to edit these fields based on 'rp_user_id' field. I have to show them and update them to database. How. Please help me.

I have ran this code before and it worked but not it won't update.  Can anyone see what I am doing wrong?



Code: [Select]
<?
if(isset($_POST[sort_invest]))   {   // if form was submitted
 
$id = $_POST['sel_record'];
$sort = $_POST['sort'];

for($i=0;$i<$count;$i++){

$sql = "UPDATE invest SET id='$id[$i]', sort='$sort[$i]' WHERE id='$id[$i]'";

$sql_result = mysql_query($sql,$con)
or die (mysql_error());
}
  }

// if form was submitted or if it came from another page
if (isset($_POST['order_invest']) || isset($_POST['sort_invest'])) {

?>       
      <p><strong>Order Invest</strong></p>
     
<form action="<?php echo $_SERVER['PHP_SELF']; ?>" method="post">     
<?   
$sql = "SELECT id, sort, title FROM invest ORDER BY sort ASC";
$sql_result = mysql_query($sql,$con) or die(mysql_error());

     while ($row = mysql_fetch_array($sql_result)) {   
            $id = $row["id"];

Hi All,

Can't get this code working. the statement works fine directly on the table, just not when executed from the PHP file:

mysql_connect("$host", "$username", "$password")or die("cannot connect");
mysql_select_db("$db_name")or die("cannot select DB");

$sql="SELECT

$result=mysql_query($sql);

The page loads fine, but just doesn't update the DB.

Thanks in advance for any help.

I am running a query to get a certain student's quiz results from all attempts and print one after the other in a simple table for now. The student is designated by an email address. I need results from all of the rows containing this particular email. The issue I think I am having is that when I use "WHERE" and specify an email address that exists many times in the table it isn't storing the variable correctly. Here is code below that I cannot get working right.

When I try to print these variables as a test to see if they are working I get nothing. No errors either. I have checked all names, spellings, and capitalization about 5 times. Thanks for looking at it.

Code: [Select]
$QuizQuery = mysql_query("SELECT * FROM Quiz_Results WHERE Email = '".$_SESSION['UserEmail']."' AND Quiz_Name = 'M1'")
or die(mysql_error());

$i=1;

while ($QuizResults = mysql_fetch_array($QuizQuery)){

$UserEmail = $QuizResults['Email'];
$Score = $QuizResults['Score'];
$Date = $QuizResults['Date_Taken'];


echo "<table width='650' border='1'><tr><td>";
echo "Attempt #".$i."<br></td><td>Sco ".$Score."</td><td>";
if($QuizResults['Pass'] == "PASSED"){
echo "Passed";
}
else {
echo "Failed";
}
echo "</td><td>Date Taken: ".$Date."</td></tr></table>";



$i++;
}

hey can someone advice me on how to make my update script update multiple rows.

here's what i've got so far:
update.php

<?php
require('connect.php');

$update = mysql_query("SELECT DISTINCT rideName FROM ride ORDER BY rideName DESC" );
$numrows = mysql_num_rows($update);

echo "<form action='mysql_update.php' method='POST'>
<select name='updateRide' >";


while ($row=mysql_fetch_assoc($update))
{
                        #$rideID = $row ['rideID'];
                        $rideName = $row ['rideName'];
                        #$seatNumber = $row ['seatNumber'];
                        #$time = $row ['time'];
                        #$price = $row ['price'];


echo "<option value='$id'> $rideName </option>";



}
echo "</select>
<input type='text' name='tochange'> 
<input type='submit' name='submit' value='change'>      
</form>";
?>


and now the handler script: mysql_update.php

<?php
require ('connect.php');

$updateRide=$_POST['updateRide'];
$tochange=$_POST['tochange'];

if ($updateRide&&$tochange)
{
$change = mysql_query("UPDATE ride SET rideName='$tochange'
WHERE $id='updateRide'");

}

?>
 




When I try this I get nothing, no changes. In the table there is 3 distinct rideNames each have more than 20 rows. Is there a way using the drop down box and ext field like i Have to update all of the distinct rideNames in the table?

Thanks.

Hi, I'm very new to these forums and php alike.  I've been working on this bit of code for weeks now.  I've written numerous versions and made endless revisions; trying pieces from many similiar source and well, it's still not quite working out for me.

The form I've been trying to finish will have multiple rows. The user will input values specific to each row, but I'm trying to make it so that each row is synonymous with each other in regard to the database table. Like an order form, an inventory form, or a roster. I'd really like to make this code work out because I can think of numerous applications for it's use. I'm sure others could use it for even more.

So, as you see; the html code represents the table that contains the form. Currently, I only have five of these rows in the form, but would like for anybody using the code to be able to add in code for as many rows in the table as needed.
Code: [Select]

In the php script I've tried using the count, loop, if, several others functions to try to get it to insert all the completed rows from the form into the table but just can't seem to get it to work out.  Anyways, here's a representation of what i'd like to achieve.  Not necessarily the code I've written trying to accomplish this, I'd have to upload a book if that were the case.

<?php 
ini_set('display_errors','On'); 
error_reporting(E_ALL); 

$host="localhost"; // Host name  
$username="root"; // Mysql username  
$password="password"; // Mysql password  
$db_name="testing"; // Database name  
$tbl_name="test_multiple"; // Table name 

// Connect to server and select databse. 
mysql_connect("$host", "$username", "$password")or die("cannot connect");  
mysql_select_db("$db_name")or die("cannot select DB"); 

//declarations 
$vendor = $_POST['vendor']; 
$description = $_POST['description']; 
$quantity = $_POST['quantity']; 
$price = $_POST['price']; 

// Check if button name "Submit" is active, do this  
$sql1="INSERT INTO $tbl_name (vendor, description, quantity, price) VALUES ('".$vendor."', '".$description."', '".$quantity."', '".$price."')"; 
$result1=mysql_query($sql1); 

mysql_close(); 
?>


If anybody can suggest where I need to go with that, that would be great.  Like I said above, I've tried about everything I could find any reason to from forum threads I had found in google searches and whatnot.  Also, if there is a good article, link or tutorial that would address this that anybody knows about that would be great.  However, I'm not looking for a link to a product or plugin that will do this stuff for me.  I'm trying to get halfway decent at php and would like to have working code for myself to build upon, modify, and learn from.  Any help is greatly appreciated!!!!
