PHP - Delete Number Modify Order
I have a mysql table with the following sequential number
Order 1 2 3 4 5 6 7 Say I choose to delete number 4, how do I create a script to subtract 1 from each number greater than 4 in the list to keep the remaining numbers in sequence? Similar TutorialsI have the following session variables for each item in a cart, which gets updated each time an item is added from the catalog // Register the session variables $_SESSION['ses_basket_items']=$ses_basket_items; $_SESSION['ses_basket_name']=$ses_basket_name; $_SESSION['ses_basket_amount']=$ses_basket_amount; $_SESSION['ses_basket_price']=$ses_basket_price; $_SESSION['ses_basket_stockcode']=$ses_basket_stockcode; $_SESSION['ses_basket_image']=$ses_basket_image; $_SESSION['ses_basket_size']=$ses_basket_size; $_SESSION['ses_basket_sizechoice']=$ses_basket_sizechoice; $_SESSION['ses_basket_id']=$ses_basket_id; I have a current cart page which loops through the sessions and displays them in a form. I have a check box for each item with the name="remove[]" and the value is the itemID which is the $ses_basket_id of item in the session. I have a select box with name="size[]" and the value is the users selected size for each item in the session which is $ses_basket_size Finnally I have a quantity text box with name="quantity[]" and the value is the users quantity value selected which is $ses_basket_amount. After all the looping through the products displaying each item in a row I have an update cart submit button name="change" outside the loop. What I want to know is how do I setup to perform each of these actions for each item in the session, how do I create the foreach loops for each array to delete or modify the correct items in the session if they are modified. I have the code to perform each task but dont know how to loop it through for each item in the session affecting only the correct session items. so if I have 3 items in the session for example, and I want to change the size of item 1, remove item 2 and change item 3 for quantity 1 to quantity 3 with only the 1 form and change button for all items and actions? Hope that makes sense any help with this would be appreciated. I posted this in mysql as well but maybe someone would know the php/mysql syntax to do this: How to re order records after a delete or move? I have table of navigational items. lets say under "about us" i have 5 sub links and i order them by a field called theorder. How can a re order them properly if one is deleted? orders are 1,2,3,4,5 and if i delete the record that is 3 then the order is 1,2,4,5 but i want it to now become 1,2,3,4. How do i do this properly? Thanks Hello all, I have used the phpfreaks custom order list script to create, well, a custom order list, but for some reason the Delete section of the code is not reassigning the numbers correctly after an item is deleted. It deletes the record okay, but if I have: 1 2 3 4 and delete 3, then 4 should become 3 but 4 stays as 4 until it moves two places and then it becomes 3. I am sure its related to part of this code, but please let me know if you have any ideas. Cheers Pockitz // delete row from table $sql = "DELETE FROM images WHERE imgsequenceid = '$seqid'"; $result = mysql_query($sql) or die(mysql_error()); if($result){ echo "Image $seqid successfully deleted from $id"; }else{ echo "ERROR"; } // select the info, ordering by sequenceid $sql = "SELECT imgsequenceid, imgid FROM images ORDER BY imgsequenceid"; $result = mysql_query($sql) or die(mysql_error()); // initialize a counter for rewriting sequenceid $seqid = 1; // while there is info to be fetched... while ($r = mysql_fetch_assoc($result)) { $imgid = $r['imgid']; // update the sequenceid number to the one in the next number $sql = "UPDATE images SET imgsequenceid = '$seqid' WHERE imgid = '$imgid'"; $update = mysql_query($sql) or die(mysql_error()); // inc to next avail number $seqid++; } // end while } // end if del Hello, Do you guys have any idea how to start an Automatic Order Number System in PHP? I have an service Website, where you can purchase something, and i want after the redirect to "Success.php" to generate an order number, to be shown to the buyer and saved in Date Base for me. Any solutions helps. I´m beginner so don´t mind
I'm getting the dreaded " Invalid parameter number: number of bound variables does not match number of tokens" error and I've looked at this for days. Here is what my table looks like:
| id | int(4) | NO | PRI | NULL | auto_increment | | user_id | int(4) | NO | | NULL | | | recipient | varchar(30) | NO | | NULL | | | subject | varchar(25) | YES | | NULL | | | cc_email | varchar(30) | YES | | NULL | | | reply | varchar(20) | YES | | NULL | | | location | varchar(50) | YES | | NULL | | | stationery | varchar(40) | YES | | NULL | | | ink_color | varchar(12) | YES | | NULL | | | fontchosen | varchar(30) | YES | | NULL | | | message | varchar(500) | NO | | NULL | | | attachment | varchar(40) | YES | | NULL | | | messageDate | datetime | YES | | NULL |Here are my params:
$params = array(
':user_id' => $userid,
':recipient' => $this->message_vars['recipient'],
':subject' => $this->message_vars['subject'],
':cc_email' => $this->message_vars['cc_email'],
':reply' => $this->message_vars['reply'],
':location' => $this->message_vars['location'],
':stationery' => $this->message_vars['stationery'],
':ink_color' => $this->message_vars['ink_color'],
':fontchosen' => $this->message_vars['fontchosen'],
':message' => $messageInput,
':attachment' => $this->message_vars['attachment'],
':messageDate' => $date );
Here is my sql:
$sql = "INSERT INTO messages (user_id,recipient, subject, cc_email, reply, location,stationery, ink_color, fontchosen, message,attachment) VALUES( $userid, :recipient, :subject, :cc_email, :reply, :location, :stationery, :ink_color, :fontchosen, $messageInput, :attachment, $date);";
And lastly, here is how I am calling it:
$dbh = parent::$dbh;
$dbh->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_WARNING);
if (empty($dbh)) return false;
$stmt = $dbh->prepare($sql);
$stmt->execute($params) or die(print_r($stmt->errorInfo(), true));
if (!$stmt) { print_r($dbh->errorInfo()); }
I know my userid is valid and and the date is set above (I've echo'd these out to make sure). Since the id is auto_increment, I do not put that in my sql (though I've tried that too), nor in my params (tried that too). What am I missing? I feel certain it is something small, but I have spent days checking commas, semi-colons and spelling. Can anyone see what I'm doing wrong?
Hi everyone. I'm very new into self learning programming. Presently I'm trying to develop a simple basic Robot that would only Place a Market Order every seconds and it will cancel the Order every followed seconds. Using the following library: It would place Trade Order at a ( Price = ex.com api * Binance api Aggregate Trades Price) I have already wrote the api to call for xe.com exchange rate with php
<?php
$auth = base64_encode("username:password");
$context = stream_context_create([
"http" => [
"header" => "Authorization: Basic $auth"
]
]);
$homepage = file_get_contents("https://xecdapi.xe.com/v1/convert_from?to=NGN&amount=1.195", false, $context );
$json = json_decode($homepage, TRUE);
foreach ($json as $k=>$to){
echo $k; // etc
};
?>
And also for the Binance Aggregate Price in JavaScript
<script>
var burl = "https://api3.binance.com";
var query = '/api/v3/aggTrades';
query += '?symbol=BTCUSDT';
var url = burl + query;
var ourRequest = new XMLHttpRequest();
ourRequest.open('GET',url,true);
ourRequest.onload = function(){
console.log(ourRequest.responseText);
}
ourRequest.send();
</script>
My problem is how to handle these two api responds and also the functions to use them to place a trade and cancel it. Hi all.

I wish to find out is there any possible that I can delete some data inside my php website but inside my sql database, the record will still at there?
Thank you.
I'm trying to set it so that it will delete an entire populated directory based upon a value in the database then after finishing that to go back and delete that row in the database. my current code is Code: [Select] <?php $page_title = "Central Valley LLC | Photo Addition" ?> <?php include("header.php"); ?> <?php include("nav.html"); ?> <div id="content"> <form action="delprod.php" method="post" enctype="multipart/form-data"> <label for="which">Choose A Product To Remove:</label> <?php $con = mysql_connect("localhost","phoenixi_cv","centraladmin"); if (!$con) { die('Could not connect: ' . mysql_error()); } mysql_select_db("phoenixi_cvproducts", $con); $result = mysql_query("SELECT * FROM Products"); echo "<select name=\"which\">"; while($row = mysql_fetch_array($result)) { echo "<option "; echo "value=\"" . $row['id'] .

I have problem durring binding update query. I can't find what is causing problem.
public function Update(Entry $e)
{
try
{
$query = "update entry set string = $e->string,delimiter=$e->delimiter where entryid= $e->id";
$stmt = $this->db->mysqli->prepare($query);
$stmt->bind_param('ssi',$e->string,$e->delimiter,$e->id);
$stmt->close();
}
catch(Exception $ex)
{
print 'Error: ' .$ex->getMessage();
}
}
When I run function update I'm getting next error:Warning: mysqli_stmt::bind_param(): Number of variables doesn't match number of parameters in prepared statement
Can you help me to solve this problem ?
Edited by danchi, 17 October 2014 - 10:25 AM. I need to display a number(the number is retrieved from the db) in the form input field such that only the last 4 digits is visbile, the remaining can be masked as * or X or whatever is applicable. I know the last 4 can be obtained as follows: Code: [Select] $number=substr($number,-4,4); But when i hit the submit button the form validates the input field and checks if the number is a valid number of a specific format. Therefore when I click on the submit button then I should still be able to unmask the masked numbers or do something similar that would help me validate the whole number. Code: [Select] <input type="text" name="no" value="<?php if(!empty($number)){ echo $number;} ?>"> I've got. Hey I have a string that looks like the following: Quote top-php-tutorials-2.html I have a script that cycles through each page. The 2 in the quote above is the page number. How can I extract the number between the - and the .html and replace it with another number? I've tried Code: [Select] substr($engine->selectedcaturl, 0,-6).$v.".html"But then I realised this only works for numbers that are 1 digit long Any input would be appreciated Hi guys, this is my first post so be gentle I have a string of ingredients, eg 1kg of salf 20kg of sugar 15kg of something nice This is the portion / mix for 1 person, I would like to make it scalable, so for example multiple all ingredients by for two people etc. So how do I do this with PHP I am guessing a regexp to look at the string and modify each number by the multiplier Any suggestions would be great thanks guys I have tried google and came up empty I think I need to convert the string to an array then modify it? John I'm wondering how I can use the following code to capture the current url...... Code: [Select] <?php function curPageURL() { $pageURL = 'http'; if ($_SERVER["HTTPS"] == "on") {$pageURL .= "s";} $pageURL .= "://"; if ($_SERVER["SERVER_PORT"] != "80") { $pageURL .= $_SERVER["SERVER_NAME"].":".$_SERVER["SERVER_PORT"].$_SERVER["REQUEST_URI"]; } else { $pageURL .= $_SERVER["SERVER_NAME"].$_SERVER["REQUEST_URI"]; } return $pageURL; } ?> <?php echo curPageURL(); ?> and then have the output modified to change the domain name and create a link. Example: before - http://website1.com/page after - http://website2.com/page I think this would be done using function modify_url, but I'm not sure how to do it, any help would be greatly appreciated. Thanks Hello All, I am trying to modify a value found in a csv file and I can't seem to figure this out. I already looked into fputcsv and cannot seem to make it work to just modify a value. I have a script now that outputs the csv into a table and displays a count for how many rows there are. I am parsing through a very large file and (for example) I want to replace all instances of the word "Norway" with "it works". Here's what I have so far: Code: [Select] <?php $filename='Test.txt'; $count=0; $c=0; echo '<table border=1>'; $file_handle = fopen($filename, "r+"); while (!feof($file_handle) ) { $parts = fgetcsv($file_handle); echo '<tr><td>'.$count.'</td>'; while($c<=3) { if($parts[$c]=='Norway') { $parts[$c]='It works'; //code to modify the csv value in the file } echo '<td>'. $parts[$c] .'</td>'; $c++; } $c=0; "</tr>"; $count++; } fclose($file_handle); echo '</table>'; ?> I have looked all over and can't find any examples of how to do this. Any help would be greatly apprecieated!!! Hi Folks, i am a bit stuck on how to proceed with the following and could use some input. I have a table with a whole bunch of zipcodes and places. A lot of the zipcodes are repeated and i would like to merge them e.g. 7 | 07677 | WOODCLIFF LAKE | New Jersey | 41.02 | -74 8 | 07677 | WESTWOOD | New Jersey | 41.02 | -74 9 | 07677 | WOODCLIFF LK | New Jersey | 41.02 | -74 What i would like to do is merge these into one line then delete the obsolete ones e.g. 7 | 07677 | WOODCLIFF LAKE | WESTWOOD, WOODCLIFF LK | New Jersey | 41.02 | -74 Obviously not all the zipcodes are duplicated, and with 70 odd thousand lines its a bit daunting to go through them manually. Any pointers would be useful. For right or wrong, I've been using XML to define my Doctrine entities. When the XML changes, my entities need to change. I've automated the process with a simple PHP script which allows me to swap some text to modify one of the auto-generated methods, add methods, etc. Kind of clunky but it works well enough. Now, I recently had the need to remove a given method in its entirety from a given class. I "could" just add the entire string which represents the method name, earlier comments, and script for the method to my parsing script to my parsing script and remove it, but would like to be a little more concise. For instance, say I have $script as follows:
$script = <<<'EOT'
class SomeEntityClass
{
//... more stuff above
public function getSomething()
{
return $this->something;
}
/**
* Get foos.
*
* @return \Doctrine\Common\Collections\Collection
*/
public function getFoos()
{
return $this->foos;
}
/**
* Get somethingElse.
*
*/
//... more stuff below
}
EOT;
How would you recommend creating the function: removeFunction($script, 'getFoos') which would remove the given function along with its comments from the $script string and result with?
$script = <<<'EOT'
class SomeEntityClass
{
//... more stuff above
public function getSomething()
{
return $this->something;
}
/**
* Get somethingElse.
*
*/
//... more stuff below
}
EOT;
Assuming regex is the way to go, I was thinking of something like the following, but could use some help with the regex expression.
function removeFunction($script, $method)
{
$method="public function $method(";
//regex to remove script with which starts after pattern "{\n" OR "**/", contains $method, and is located before pattern "\n{" OR "\n /**"
return $script;
}
Thanks how do I modify the date coming from the database in YYYY-MM-DD format to MM-DD-YYYY? |
