Please read before bidding. You must have skills in Php, Yii, Mysql, Bootstrap, CSS. The DataSchool project is a school management system designed to manage multiple school online. A principal can suscribe and create his school online. The system is developped with Php, yii framework and Mysql. It is user-friendly, with many options to manage schools. User can create his school online and enroll students, teachers, etc. When create students, teachers or professors, we can also create or not user with related profils. We use rights extension (Yii to manage user). We have 5 profils : admin (have rights on the whole system), principals (have rights on all the students, teachers, homeworks, exams for his school), teacher (rights on his courses and his classes), students (have righsts on his profil, and his homeworks), parents (rights on his students). Technologies used : Mysql Php Yii framework (rights extension) Bootstrap And a theme (themeforest). We need to add some features : Features to add: Multiple language in the software : French, English and creole Add a search feature for multiple table (search for student, parents, professor, exams or homework in one search field ). Generate and print report (bulletin) in pdf for student by exam ( 2 format : a general report and a individual report). We need to fix some bugs : Bugs to fix : Fix Date issue with format as dd/mm/yyyy when saving and in some views Fix the ajax issue in the back end. Filter and pagination don't work with the theme for the back end. Set the slideshow and the foot of the frontend to wide (100%) of the screen as it is on the template Fix students picture in forms and views. show picture when select it before save student in the form. Activate the user creation feature checkbox automatically if email field is checked. Generate a code for student if the checkbox code is checked in student’s form. Fix list view of student to show them by column with picture. Fix the menu in the backend to collapse or show it full as it is in the original theme. Fix it to have submenu as the original theme. Send email when : create user (students, parents, teacher) create homeworks or exam (send to all students and parents related to class or courses) Fix rights user to see only authorized data or menu. Ex: parent can see only his students even if they put an id in the browser. Principal for a school can see only students of his school. Hide [login to view URL] in the URL. Fix it to work with login. Add feature to choose each course by class when create an exam. When create exam, the list of class with checkbox to choose classes. We must have option to choose wich course by class too. Fix bug for subdomains (wildcard) by school. Each school can have his own URL (like : [login to view URL], myschool is the name of the school). You have to fix it this error cause it don’t work now. The link to DataSchool : [login to view URL] the theme used for backend is : [login to view URL] More info and access to ftp and the database will be given to the freelancer.
