+
+This involves developing web pages, run on your BOINC server,
+for submitting jobs.
+These pages are application-specific,
+since the way that users specify parameters and input files depends on the application.
+
+These scripts are best implemented in PHP.
+BOINC provides a large set of PHP APIs for accessing the BOINC database,
+staging files, and so on.
+
+These scripts will typically use BOINC PHP code for various purposes:
+
+ * '''inc/util.inc''': utility functions
+ * '''inc/boinc_db.inc''': access to BOINC database
+ * '''inc/submit_db.inc''': access to job-submissions parts of BOINC database 
+ * '''inc/submit_util.inc''': job submission utility functions
+
+== Authorizing requests ==
+
+Job-submissions scripts must check that the user is allowed to submit jobs.
+You can do this as follows:
+{{{
+$user = get_logged_in_user();
+$user_submit = BoincUserSubmit::lookup_userid($user->id);
+if (!$user_submit) error_page("no submit access");
+$app = BoincApp::lookup("name='lammps'");
+if (!$app) error_page("no lammps app");
+if (!$user_submit->submit_all) {
+    $usa = BoincUserSubmitApp::lookup("user_id=$user->id and app_id=$app->id");
+    if (!$usa) {
+        error_page("no submit access");
+    }
+}
+}}}
+
+== Creating batches and jobs ==
+
+You can create a batch as follows:
+{{{
+$batch_id = BoincBatch::insert(
+    "(user_id, create_time, njobs, name, app_id, state)
+    values ($user->id, $now, $njobs, '$batch_name', $app->id, ".BATCH_STATE_IN_PROGRESS.")"
+);
+}}}
+
+Create jobs using the [JobSubmission#creatework-tool create_work script].
