Postgress Tips and Tricks

This summary is not available. Please click here to view the post.

Mercurial: Tips and tricks

1. Usage: Completely remove a named branch.

$: hg strip "branch(${BRANCHNAME})"

2. Now re-iterate for all the branches you have, that's it

$:hg pull -u

3. To check if you have any unwanted changes

$:hg outgoing

4. Add, Remove tag

$:hg tag -r newrevisionhash stable
$:hg tag --remove stable

5. Incoming and Outgoing

$:hg incoming
$:hg incoming -p
$:hg incoming -b <branchname>
$:hg incoming -p -b <branchname>

6. Copy files across branches

$:hg update -r to-branch
$:hg revert -r from-branch file
$:hg ci -m 'copied single file from from-branch to to-branch

7. Dirty merge If both branches have made changes to a file that you want to keep, a dirty trick would be to create a merge of the two branches using hg merge, possibly/probably on still another branch, check that in, and then copy a single file between the merge and the to-branch(Reference: Stackoverflow)

$:hg update -r to-branch
$:branch merge-branch
$:hg merge -r from-branch
$:hg ci -m 'temp merge to be discarded"
$:hg update -r to-branch
$:hg revert -r merge-branch single-file
$:hg ci -m 'merged single-file from from-branch to to-branch"
$:hg strip merge-branch

8. To see heads in a particular branch <branch name>

$:hg heads <branch name>

9. To commit as a user <userDisplayName>

$:hg commit -u <userDisplayName>

Mysqli Bind dynamic parametere

Trying to create a function to insert data into a SQL table, using MySQLI. I want to create a generic function, to insert different types of data in different databases.
The issue is at binding the parameters. I can't find a good way to bind them, as I've got multiple variables with values and keys, but they're all in array format, and  bind_param  requires a new variable for each

$sql = 'SELECT id, lastname FROM customers WHERE ' .
  'category = ? AND ' .
  'lastname LIKE ?';

/* Prepare statement */
$stmt = $conn->prepare($sql); if($stmt === false) {
  trigger_error('Wrong SQL: ' . $sql . ' Error: ' . $conn->errno . ' ' . $conn->error, E_USER_ERROR);
}
 
$category_id = 1;
$lastname = '%Smith%';
 
/* Bind parameters. Types: s = string, i = integer, d = double,  b = blob */
$stmt->bind_param('is', $category_id, $lastname);
 
/* Execute statement */
$stmt->execute();
 
/* Fetch result to array */
$res = $stmt->get_result();
while($row = $res->fetch_array(MYSQLI_ASSOC)) {
  array_push($a_data, $row);
}

The problem
$stmt->bind_param() does not accept params array. So, how to bind params, if their number is variable, depending on user input in your application?

A workaround is to use call_user_func_array to pass dynamically the params array.

The solution
In the following code:

$conn is the connection object

$a_bind_params is the array of the parameters you want to bind

$a_param_type is an array with the type of each parameter (Types: s = string, i = integer, d = double, b = blob). This is another disadvantage of MySQLi API. You have to maintain this array some way in your application.

With call_user_func_array, array params must be passed by reference. See notes in manual page.

The code:

/* Bind parameters. Types: s = string, i = integer, d = double,  b = blob */
$a_params = array();
 
$param_type = '';
$n = count($a_param_type);
for($i = 0; $i < $n; $i++) {
  $param_type .= $a_param_type[$i];
}
 
/* with call_user_func_array, array params must be passed by reference */
$a_params[] = & $param_type;
 
for($i = 0; $i < $n; $i++) {
  /* with call_user_func_array, array params must be passed by reference */
  $a_params[] = & $a_bind_params[$i];
}
 
/* Prepare statement */
$stmt = $conn->prepare($sql);
if($stmt === false) {
  trigger_error('Wrong SQL: ' . $sql . ' Error: ' . $conn->errno . ' ' . $conn->error, E_USER_ERROR);
}
 
/* use call_user_func_array, as $stmt->bind_param('s', $param); does not accept params array */
call_user_func_array(array($stmt, 'bind_param'), $a_params);
 
/* Execute statement */
$stmt->execute();
 
/* Fetch result to array */
$res = $stmt->get_result();
while($row = $res->fetch_array(MYSQLI_ASSOC)) {
  array_push($a_data, $row);
}

Implement multi file upload using blueimp library

If you want to do some customization in the interface, behaviour etc., I have an example.
I customised the behaviour as per below requirements.
Requirement:
Interface: 
Create a file selector, 
That can select multiple files, 
On selecting files, start uploading images
Show a single progress bar
Display a thumbnail of files selected with a contol(may be a cancel button) near to thumbnail preview to cancel upload of that image only

Drop and Drop Files Here

Upload Files

If you want to do some customization in the interface, behaviour etc., I have an example.
I customised the behaviour as per below requirements.
Requirement:
Interface: 
Create a file selector, 
That can select multiple files, 
On selecting files, start uploading images
Show a single progress bar
Display a thumbnail of files selected with a contol(may be a cancel button) near to thumbnail preview to cancel upload of that image only

Drop and Drop Files Here

Upload Files

If you want to do some customization in the interface, behaviour etc., I have an example.
I customised the behaviour as per below requirements.
Requirement:
Interface: 
Create a file selector, 
That can select multiple files, 
On selecting files, start uploading images
Show a single progress bar
Display a thumbnail of files selected with a contol(may be a cancel button) near to thumbnail preview to cancel upload of that image only
