drupal - How do I programmatically delete user profile picture? -

-

I have the following code to upload a program image in an existing user account (which I have found on the internet). I'm still getting the " Duplicate entry " error

So I thought I should remove the existing photo first (if any) before uploading the first picture ) Or is there a better way to overwrite without getting the error?

DOException: SQLSTATE [23000]: Integrity Constraints: 1062 For Duplicate Entry '' Key 'Yuri': {file_managed} (UID, Yuri , Filememes, files, status, timestamp, type) values ​​((db_insert_placeholder_0 ,: db_insert_placeholder_1 ,: db_insert_placeholder_2 ,: db_insert_placeholder_3 ,: db_insert_placeholder_4 ,: db_insert_placeholder_5 ,: db_insert_placeholder_6); Array ([: db_insert_placeholder_0] => 1302 [: db_insert_placeholder_1] => [: db_insert_placeholder_2] => image / png [: db_insert_placeholder_3] => 143769 [: db_insert_placeholder_4] => 1 [: db_insert_placeholder_5] => 1414500789 [: db_insert_placeholder_6] = > Image) in drupal_write_record () (line 7202 /home1/public_html/example/includes/common.inc).

Here's the code I am using: 

  $ obj_tochange = user_load ($ user); $ Image_path = 'http: //www.example.com/sites/default/files/photo_gallery/newphoto.png'; $ Image_info = image_get_info ($ image_path); // Create a file object $ file = new stud class (); $ File- & gt; Uid = $ obj_tochange- & gt; Uid; $ File- & gt; Yuri = $ image_path; $ File- & gt; Filemime = $ image_info ['mime_type']; $ File- & gt; Position = FILE_STATUS_PERMANENT; $ File- & gt; Filesize = $ image_info ['file_size']; File_save ($ file); $ Edit ['picture'] = $ file; User_save ($ obj_tochange, $ edit);

You need to copy the file before calling. If it matches any other file on the server, then it should be automatically converted to file path, so it will not throw away this error. 

  $ file = new StdClass (); // This is $ file = file_copy ($ file, 'public: //', FILE_EXISTS_RENAME) as your code; File_save ($ file);

c++ - Cassandra datastax cpp driver - avoiding unnecessary copies -

-
I use the following method to create my insert statement for Cassandra (using datastax cpp driver) : ssStmt1 & lt; & Lt; "Insert some table (...) value (....)" string sStatement1 = ssStmt1.str (); Castestring cass1 = cass_string_init (sStatement1.c_str ()); CassStatement * pStmt1 = cass_statement_new (cass1, 0); I have also tried the following: CassString cass1 = cass_string_init ("Enter some table (id, date, c) value (? ,?,?); "); CassStatement * pStmt1 = cass_statement_new (cass1, 3); Cass_statement_bind_uuid (pStmt1, 0, uuidKey); Cass_statement_bind_int64 (PSTMT1, 1, timestamp); Cass_statement_bind_string (pStmt1, 2, sSomething); The first pattern works with mixed keys, the second is not. The key has a timestamp and a UUID. Timestamp is one of two errors in the field (based on the used bond statement). If bound in this way: cass_statement_bind_int64_by_name (pStmt1, "date", timestamp); I get the following error: Inva...
