  • How should i store availability calendar information in mysql? for [id] [date] [available/unavailab

    - by Haroldo
    I'm building a simple calendar for holiday cottages to show when they are booked or available. What would be the fastest mysql table design for this, bearing in mind when users mark dates as available/booked they will do so via a start date and an end date. i can see 2 obvious options Store 'booked' data for every day [more rows] or, store 'booked' data with 2 columns a start_date and end_date [more processing?] Which is best or is there another method i'm missing?

  • MySQL LEFT JOIN issue with three WHERE statements

    - by jhat
    I am building a note taking app for myself with tag filtering functions, but am having an issue when trying to grab notes with the tags. The tag filter needs to use AND not IN, because it will help better narrow down what I am looking for. My tables are configured like this: + notes note_id | note_title | note_uid + tags tag_id | tag_title + notes_tags nt_id | nt_note_id | nt_tag_id The notes_tags table keeps track of all notes' tags. I am not worried about returning any information about tags, so here is an example LEFT JOIN I am using currently to only get notes with only 1 tag. SELECT * FROM notes_tags LEFT JOIN notes ON note_id = nt_note_id WHERE note_uid IN ( 1 ) AND nt_tag_id = 10 This query runs perfect, it grabs all of the notes with that single tag. However, I am having issues "pinpointing" my notes using a query like this: SELECT * FROM notes_tags LEFT JOIN notes ON note_id = nt_note_id WHERE note_uid IN ( 1 ) AND nt_tag_id = 10 AND nt_tag_id = 11 What am I doing wrong with the syntax?

  • Wordpress Hooks vs. includes?

    - by Chris J. Lee
    This is somewhat a subjective question. Noticed themes like thematic and carrington use hooks to display their themes. Trying to figure out which works best for a more efficient workflow. Which seems more efficient at theming? Trying to weigh in the cons and pros of hooks vs. just including static files.

  • Setting an empty default value for a char-column in MySQL?

    - by user281434
    Hi In phpMyAdmin I have a char(32) column that has no default value(ie. Default: None). When I try to insert data through a SQL query, it throws out an error saying that the column "doesn't have a default value". I need it to be empty, so instead I've just set it's default value as "As defined: " and then nothing in the value field. Is this a bad idea? And is it any better than simply throwing in an empty value for the column in the SQL query? Thanks for your time.

  • How can I split a list with multiple delimiters?

    - by Rob
    Basically, I want to enter text into a text area, and then use them. For example variable1:variable2@variable3 variable1:variable2@variable3 variable1:variable2@variable3 I know I could use explode to make each line into an array, and then use a foreach loop to use each line separately, but how would I separate the three variables to use?

    - by Sahal
    How can i see how many number of connections are opened in one request. (mysql_connect) I know that if i call mysql_connect function 100 times, function will return the connection link which is already opened only if parameters of the function is same.

  • For securing forms, when do I issue the token?

    - by AQuestionADayKeepsTheDrAway
    So, I have a form, to make it a little more secure and potentially help prevent CSRF attacks I want to add a random token value in a hidden field that value is also stored server side in my session data. When should I issue a new token? Per form? Per page load where there is any form? Per session? I can render it invalid as soon as a form is successfully submitted but I'm wondering when to generate one. I ask as if I issue it per form or per page do I not risk the chance of a duplicate token value overwriting the existing (valid) token if a user opens a separate window but submitting the first form (with the now overwritten value)?

  • Zend Framework-does every webpage have it's own controller and indexAction and view?

    - by Joel
    I'm wanting to be sure that I am setting things up correctly. On a typical website with 10 pages, would each page have it's own controller with it's own IndexAction and it's own View folder with it's own index.phtml as a view? Or do you have one controller with multiple Page1Action, Page2Action, etc and have multiple differently named view.phtml pages within view/index folder? I'm leaning toward the former because then I can have a cleaner controller for each page... Is there a standard, or is it subjective?

  • WordPress [img] tags

    - by Lokheed
    Hey guys, I'm trying to allow that standard BB [img] [/img] tags on my WordPress blog. I got this snippet from the net, but it only works on lower case [img] tags. I'd like it to apply to both [img] and [IMG]. As you can tell, I'm totally not a coder. function embed_images($content) { $content = preg_replace('/\[img=?\]*(.*?)(\[\/img)?\]/e', '"<img src=\"$1\" alt=\"" . basename("$1") . "\" />"', $content); return $content; } add_filter('comment_text', 'embed_images'); I know '||' is 'or' but don't know enough coding to make the changes. Any help is greatly appreciated. Thanks.

  • preg_replace replacing with array

    - by Scott
    What I want to do is replace the "[replace]" in input string with the corresponding vaule in the replace array. The total number of values will change but there will always be the same number in the replace array as in input string. I have tried doing this with preg_replace and preg_replace_callback but I can't get the pattern right for [replace], I also tried using vsprintf but the % in <table width="100%"> was messing it up. All help is greatly appreciated! Replace Array: $array = array('value 1','value 2','value 3'); Input String $string = ' <table width="100%"> <tr> <td>Name:</td> <td>[replace]</td> </tr> <tr> <td>Date:</td> <td>[replace]</td> </tr> <tr> <td>Info:</td> <td>[replace]</td> </tr> </table> '; Desired Result <table width="100%"> <tr> <td>Name:</td> <td>value 1</td> </tr> <tr> <td>Date:</td> <td>value 2</td> </tr> <tr> <td>Info:</td> <td>value 3</td> </tr> </table>
