I am very frustrated with my one old month problem. This is my first web page and it's quite complicated (for me).
My problem is with AND and OR in filtering categories in google maps. All tutorials go in the direction of the OR (golf OR theather). What about Golf and London? The more boxes checked, the less markers on the map.
I have two questions:
(1)
I am trying to follow this tutorial. I guess this is a trivial question: where is the data that is displayed in the panel? (I have followed several other tutorials and never had problems with finding the data, but this one...). I believe this tutorial may solve my second question below.
(2) The goal is to have a real estate page where user-sellers can insert properties for sale and user-buyers can view it, filtering the the data by multiple checkbox and/or drop down menus.
The problem I have is that I can't find a way to coordinate the OR and AND.
OR: I could use the Mike's tutorial and I have studied it very carefully.
I didn't find any tutorial when the filters get more complex.
(2B) I tried to work with my old post, and it works with OR as well. but couldn't find the right code when user only checks one (or two) box (like anything in Berkeley). The code(based on the kind Jobsen's code) required user to fill out all checkboxes all the way to the end, then the marker would show up. Couldn't check only 2 boxes and leave others unchecked. Sometimes I want the first filter (City) to be filtered a second time (Bedrooms). Not add any Berkeley + Bedrooms (2 or 3 or 4). Or only Berkeley. Or Berkeley +zip code + type + bedroom OR any combination. The and / or were not working as expected.
Any help with any of the above will be greatly appreciated. Feel free to add any info in the old post as well.Thank you again for your time.
Answer for the question (1) above, pick one:
(a) CSV file; then take a look at this.
(b) stackoverflow question and answer;
(C) you tube;
i chose CSV format. Here is a screenshot to turn csv format into a table using phpmyadmin.
To do the static tutorial which requires only CSV file and not Json (no need to mess with phpmyadmin): download the csv document, but don't open and save it as csv from MS Excel. Saved it inside the notepad as csv file. No idea about google docs.
Any help with the other part of my question (how to filter database with Jquery or Javascript) will be greatly appreciated.

A couple years ago I had a client with a limited budget and a short deadline who wanted a sortable searchable table of their parts inventory online - at the time they had only an excel spreadsheet. I created a database, then I just used Script Artist (because I had it) to do the front end. It all works great and he's been happy with it, except now we'd like to make sure that Google can actually find all 17,000+ parts they have available and not just the first 25.
The page where the inventory is located is just www.thesite.com/inventory.php and the url remains the same no matter what page you're on.
I've been looking around at different options, using pushState vs html snapshots, and I'm not sure what would be the best option or if I can even do anything with the current Script Artist setup or if I should just pitch the whole thing. I'd really rather not have to start over since he still doesn't have much of a budget, so if anyone could give me any input that would be helpful. Thanks.
This is kinda confusing, so forgive me if you don't understand what I am asking. I'm trying to develop my skills and I wanted to move onto images as a next step. I did a bit of searching and I thought a good way to try this would maybe be to generate military ribbon racks depending on the options the user selects.
(See something like this as an example: http://www.ribbon-rack-builder.com/ribbons/build/4)
Now, from looking at the source code I can see that the creator of that website creates a form with all of the different ribbons and allows the user to select the ones they want with checkboxes. This form is then posted to some PHP on the page somewhere.
Being new to the image concept I have no idea what kind of PHP this would be. Could anyone give me an idea of how this website could do this and where I should start should I want to create something similar?
Thanks very much!
First, you'll need to get which checkboxes were checked:
Set the name in the form to check_list[] and you will be able to
access all the checkboxes as an array($_POST['check_list'][])
Second, you'll most likely want to use the GD and Image Functions built into PHP.
There is a lot there, and it can be confusing, so I suggest you do some reading through questions on SO on the subject: https://stackoverflow.com/search?q=merge+image+[php]
I have searched for help with this extensively but haven't been able to figure it out. This is my first attempt at asking a question here so please bare with.
I have a project called www.farmathand.com where farmers keep track of their field activities through multiple pre-defined forms and a few dynamic forms. These forms then have an associated date with them to keep a record of when something was done. Here's a screen shot
Farmers have the ability to export all their entered information into an excel file. The problem I am having is figuring out a solution so sort the activities by date. Currently I have simple export code that looks and print data from each table (i.e. each type of activity) then moves on the to the next able. The fields in each table differ as you can see in the image.
Here is a screen shot of an excel file for the above example:
What i would like to be able to do is sort the activities by the date. So in the example in the above image. Line 7 would be at the top or like one should be line 6.
I was wondering if anyone had any suggesting or could guide me to the appropriate reference. The data base is a mysql database. I'm running php scripts currently.
If I understand your question correctly then what you want is to include an ORDER BY clause in your select query to sort the data. More information here:

I am new in coding and sufferin from some basic issues. I searched for a topic to find the answer that I need but I could not find. I've been trying to write and searching codes for writting into xls file for 3 days but could not find a suitable one. The problem is:
I created a page with textareas and submit/reset button like that and I've got an excel table in document classgrades.xls. The colums of that table are named Name, Midterm1, Midterm2, Final, Attendance and Average.
Now, I am trying to write a code which automatically adds a new row and writes user inputs from textares into the excel table. If you help I appreciate very much and if you write the code briefly I can understand better.
The class I use to modify Excel documents is PHPExcel. Was at http://phpexcel.codeplex.com/ but I just googled and it's moved to GitHib https://github.com/PHPOffice/PHPExcel.
Small warning: I have found it occasionnally buggy (turn off "NOTICE" and "WARNING" errors before diving in, for example - or at least you did when I last used it) but otherwise it's easy to use.
It has some nice classes to navigate the workbooks and add rows. No point quoting examples here as there are lots of examples in the "test" section. https://github.com/PHPOffice/PHPExcel/tree/develop/Tests Use those and piece together what you need.
This question might seem strange but I have been searching for an answer for a long time and I couldn't find any.
Let's suppose you have a blog and this blog has many post entries just like any other blog. Now each post can have simple user comments. No like buttons or any other resource that would require data management. Now the query is: Can I store user comments on a single text file? Each post will be associated to a text file that holds the comments. So, if I have n posts I'll have n text files.
I know I can perfectly do this, but I have never seen it anywhere else and no one is talking about it. For me this seems better than storing all coments from all posts in a single mysql table but I don't know what makes it so bad that no one has implemented it yet.
Storing comments in text files associated with corresponding post? Lest see if it's good idea.
Okay adding new comments easy - write new text to the file. But what about format of your data? CSV? Ok then you would have to parse it before rendering.
Paging. If you have a lot of comments you may consider creating paging navigation for it. It can be done easily, sure. But you would need to open the file and read all the records to extract say 20.
Approve your comments. Someone posted new comment. You place it with pending status. So.. In admin panel you need to find those marked comments and process then accordingly - save or remove. Do you think it's convinient with text files? The same if use decided to remove its comment himself.
Reading files if you have many comments and many posts will be slower the it would be in case of database.
Scalability. One day you deside to extend you comments functionality to let one comment to respond to another. How would you do it with text files? Or example from comments by nico: "In 6 months time, when you will want to add a rating field to the comments... you'll have a big headache. Or, just run a simple ALTER query".
This is just for beggining. Someone may add something.
Well, there are good reasons why this isn't done. I can't possibly name them all, but the first things that come to mind:
Efficiency
Flexibility
Databases are much more efficient and flexible than plain text files. You can index, search and assign keys to individual comments and edit and delete any comments based on their key.
Furthermore, you'd get a huge pile of text files if the blog is quite big. While in itself that's not a problem, if you all save them in one directory, it can grow out of proportion and really increase the access time needed to find and open a specific text file.
