Lab Exercises: HTML, PHP, CSS and JavaScript

由LE PHUONG撰写

The aim of these exercises is for you to build some simple web pages and to make sure you know how to use our systems for web development.

现在提到了代写服务，肯定很多人都不会觉得陌生，就算是国内也是有着专业代写作业的服务行业的，能够为有需求的学生提供很多的帮助，不过其实代写机构在国外会更获得学生的支持，这是因为国外的学校对于平时的作业要求比较严格，为了获得更高的分数顺利毕业，不少留学生就会让代写机构帮忙完成作业，比较常见的作业代写类型，就是计算机专业了，因为对于留学生来说这个技术对于Machine Learning或者AI的代码编程要求更高，所以找代写机构完成作业会简单轻松很多，那么代写机构的水平，要怎么选择才会比较高？

1、代写机构正规专业

不论是在什么情况下，选择正规合法经营的机构肯定是首要的操作，这也是为了避免自己在找机构的时候，出现上当受骗的现象，造成自己的经济出现损失，带来的影响还是非常大的，所以需要注意很多细节才可以，所以在这样的情况下，代写机构的选择，也要选择在经营方面属于正规合法的类型，这样才可以保证服务进行的时候，不会出现各种问题，也可以减少损失的出现，而且正规合法也是代写机构的合格基础。

2、代写机构编程能力

作业的难度相信很多人都很熟悉，特别是对于AI深度学习或者是人工神经网络这种算法来说，因为要对SVM、Design Tree、线性回归以及编程有很高的要求，可以说作业的完成要求非常高，因此才会带动代写机构的发展，找专业的代写机构，一般都是会有专业的人员帮忙进行作业的完成，因为这类型的作业对专业要求比较高，因此代写机构也要具备专业能力才可以，否则很容易导致作业的完成出现问题，出现低分的评价。

3、代写机构收费情况

现在有非常多的留学生，都很在意作业的完成度，为了保证作业可以顺利的被完成，要进行的相关操作可是非常多的，代写机构也是因为如此才会延伸出来的，在现在发展也很迅速，现在选择代写机构的时候，一定要重视收费情况的合理性，因为代写作业还是比较费精力的，而且对于专业能力要求也高，所以价格方面一般会收取几千元至万元左右的价格，但是比较简单的也只需要几百元价格。

4、代写机构完成速度

大部分人都很在意代写机构的专业能力，也会很关心要具备什么能力，才可以展现出稳定的代写能力，其实专业的代写机构，对于作业完成度、作业完成时间、作业专业性等方面，都是要有一定的能力的，特别是在完成的时间上，一定要做到可以根据客户规定的时间内完成的操作，才可以作为合格专业的代写机构存在，大众在选择的时候，也可以重视完成时间这一点来。

现在找专业的CS代写机构帮忙完成作业的代写，完全不是奇怪的事情了，而且专业性越强的作业，需要代写机构帮忙的几率就会越高，代写就发展很好，需求量还是非常高的，这也可以很好的说明了，这个专业的难度以及专业性要求，才可以增加代写机构的存在。

The following tasks should be done in a plain text editor and saved as .html, .php, .css, or .js files where appropriate.

You should then copy these files to DEVWEB. If you use Linux or Unix, go to the DEVWEB directory then to the 2015 directory (if you do not have a 2015 directory you will have to create one). If you put a file called ex.html in that directory you can view it in your web browser from any internet connected computer.
If you use Windows on any of the Departmental machines you will find the DEVWEB folder mapped to your Q: drive.
These exercises are worth up to 10% of the overall mark for CS 952 Database and Web Systems Development.

Submission

Please note that some of the later questions ask you to build on your solutions to earlier questions. You should therefore make sure that you save your solution to each question in separate files and that you do not overwrite your earlier solutions. For example, the solution file for question one could be named q1.html, the solution files for question 2 could be named q2.html (this will be a modified version of q1.html) and q2.php, the solution files for question 3 could be named q3.html (this will be a modified version of q1.html or q2.html) and q3.php (this will be a modified version of q2.php). The files that you create for each question should be placed in a directory or folder which you should zip and upload via Myplace.

Q1 HTML Simple form example

Using the following script showallparameters.php as your server action (and using the POST method), code the following form using HTML forms and check the correct data is sent to the server:
The job categories are “Marketing”, “Human Resources” and “Technical Support”. Don’t worry about the right alignment of the textual labels, but after you have a simple form working you should embed it in a table so that the form entry elements are nicely aligned. Also, if you wish, add some JavaScript error correction to check that something is entered in Name, Telephone, E-mail, Gender and Days Available (this is tricky).
You may wish to use http://validator.w3.org/ with advanced options to make sure that your file conforms with W3 open standards.

Q2: PHP

Write a decent handler for the form in Q1 which shows the data nicely formatted back to the user.
Add code to this PHP script to send a fixed email to you whenever the form is submitted. See PHP: mail – Manual for mail manual and Google for examples.
Change this code so that the email contains the same information echoed back to the user.

Q3: MySQL

Design a single table database to store the values from the form in Q1.
Create this database in phpMyAdmin on devweb2015 then update your PHP from Q2 to save into the database rather than emailing you.
Test your submissions using your form and phpMyAdmin to view the submissions.

Q4: PHP Error Checking

Add code to the PHP in Q1..3 to check:

The name is completed
The telephone number is complete
The e-mail is complete (you could try using regular expressions)
One of Male or Female is selected
At least one day is selected [tricky]

Add PHP so that if the name field is all capitals, it is changed to Title Case before storing.

Q5: CSS

Write HTML for the left-hand image on the last page.
Add CSS styling to make the page look like the right-hand image with minimal changes to the HTML (you only need add class and id statements) (NB: the band at top bottom is dark blue, rest of page has light blue background)
Create a CSS box in the middle of the page with maximum width 700 pixels and a nice water like image outside this box.
Add a horizontal navigation menu at the top of the page with sections for “accommodation”, “local information”, and “weather”.

Q6: Extensions

Recode the checks in Q4 in JavaScript. [Why would you do this?]
Add two date fields to your form from Q1 for “Application Date” and “Job Start Date” then

Add JavaScript to check the fields are date formatted
Add JavaScript to check that the job start date is after the application date
Add JavaScript to copy the value of the application date to the start date if it changes, and the user hasn’t yet entered a start date

If you wish you may find a public domain Calendar function in JavaScript and include this in your code to show a little calendar for the start date.
Add an administrator interface for your database in Q3 that allows the user to view all submissions and delete rows – use phpMyAdmin to create the SQL for deletion and then copy that into PHP.
Finally add a new script (PHP page) that shows a specific row of the table nicely formatted for printing as a job application and link this into the table view (i.e. have a “print me” button link).
