  2. Some general rules and things to know about PHP • Example on Pg 13 – Listing 1.1 • Html code is enclosed in angles < >, PHP uses the same format • In general you use lower case for commands • <table border=“0”> - note the double quotes • This means that it is a literal, a value being supplied • Each command that is started has to be ended • Eg < table > has to end with </table> • You use a plain text editor such as notepad (within windows) to write your code. You can not use MS Word or Wordpad

  3. Listing 1.1 • Let’s look a bit at the code • So < form action=“processorder.php” method=“post”> • Means this is a form we are creating, named processorder.php and we are going to post it or show it • <table border=“0” means create a table that I am defining • < tr bgcolor=“#cccccc”> create a row in the table • <td width=“150”>Item</td> this creates a column in the row, size 150 and put the text Item in it., end the definition with </td> • <td width=“15”>Quantity</td> create a second column, width 15, put Quantity in it • </tr> end of the row definition

  4. Listing 1.1 continued • Next row <tr> is all that is needed because the widths are known • <td>Tires</td> put tires in the column • <td align=“center”><input type=“text” name=“tireqty” size=“3” maxlength=“3” /></td> • </tr> • This one is complicated looking isn’t it – • So lets take it apart:

  5. Listing 1.1 continued • <td align=“center”><input type=“text” name=“tireqty” size=“3” maxlength=“3” /></td> • This column is going to get input, we know this because it says input type=“text” • The input will be centered • The name of the input is tireqty • The size of the input is 3 and the maximum size is 3

  6. Listing 1.1 continued • Last thing for this listing is: • <tr> • <td colspan="2" align="center"><input type="submit" value="Submit Order"></td> • </tr> • </table> end definition of the table • </form> end definition of the form

  7. <td colspan="2" align="center"><input type="submit" value="Submit Order"></td> • Colspan=“2” says this row will span both columns making it like one • The contents of the column will be centered • The input type is “submit” • With a value of “Submit Order” • This creates a submit button
