I'm wondering if it's possible to:
I have some string (10.07.2016-17.07.2016 , 19.07.2016-21.07.2016 , 22.07.2016-29.07.2016 etc... )
dates are separate by "," so for now i want to make array of dates separated by ",".
As result i will use this array to create select dropdown, so user can select data like for example (very generic, not cakephp style but it's just for understanding my question):
<select>
<option>10.07.2016-17.07.2016</option>
<option>19.07.2016-21.07.2016</option>
<option>22.07.2016-29.07.2016</option>
</select>
But now i'm wondering - how can i first filter this data to remove dates from past ?
Let's say that i have 11.07.2016 in calendar, so i should not see this in select ?
So, my question is - is this possible ? If yes, how should i filter this data? Filter array first using some function, or when i will generate select in form ?
Thanks for ideas.
first convert string into array,
$myString = "10.07.2016-17.07.2016, 19.07.2016-21.07.2016";
$myArray = explode(', ', $myString);
then use foreach to check if date is in the past
foreach($myArray as $element) {
if(strtotime($element)>strtotime("now")){
$futureDates[] = $element;
}
}
then you have only future dates for echo in
<select><option>...</option><option>...</option></select>

I'm trying to get my Highcharts graph to work. The Reason I'm having so much trouble with it this time is because I have to keep the program adaptable for future changes when it comes to my columns(named issues1 through 12).
The Goal is pretty simple, I just need to grab the issues between hours 1-12 during a certain time period, then create a graph.
My idea Is that I should create a view that organizes the desired information because there is a lot more to that table that I left out, and then create an SQL to organize the data from there. Which I realize might be overkill, but I'm an intern and my supervisor probably did it to help make it simple for me.
There are 4 different places I need to use SQL to make the Table work.
X-Axis
Day shift numbers
Swing shift numbers
Night shift numbers
So for my code The X-Axis, It works fine for just calling in the names.
xAxis: {
categories: [
<?php
foreach ($xAxisresult as $Xrow) {
echo "'" . $Xrow['IssueName'] . "'" . ',';
}
?>
]
I believe the Day/Swing/Grave SQL statements should all be similar so I'm just going to focus on one. But this is where the problem starts with how I have it set up. I tried to run an If statement were I compare the two arrays I have set up and try to match the IssueName Columns.
name: 'Day',
data: [
<?php
foreach ($Dresult as $Drow) {
if ($Xrow['IssueName'] == $Drow['IssueName']){
echo $Drow['Issues'] . ',';
}
else{
echo $Drow['Issues'] . ',';
}
}
You guys can most likely see a lot of whats wrong here. But I need to make a loop or array that will find out that if there is an empty spot in the array and output a 0 so the data stays correct.
Sorry for the wall of Text, I just wanted to give you guys as much information as possible.
To answer your question how to create an array that holds zero values and merge with the data array (I assume).
You can use array_fill to create the array with zeros, and use array_replace to replace with the data array.
$arr = array_fill(0, 10, 0); //[0,0,0,0,0,0,0,0,0,0]
$data = [2 => 15, 5 =>10, 7 => 16]; // your data
$new = array_replace($arr, $data);
var_dump($new); // [0,0,15,0,0,10,0,16,0,0]
With the updated code below, my search is working, but only using the last word in the Array. Is there a way to search the MySQL column using all words the user inputted?
Note: All input sanitization and escaping is completed in my code but not shown here.
I have two PHP arrays: $search_exploded (user inputted search terms) and $metaphoneArr (metaphones of keywords in MySQL).
I'm cycling through $search_exploded and $metaphoneArr, and if the Levenshtein is less than 2, then I'm adding the metaphone element to a third array called $levenResultsArr.
In MySQL, I'm joining two tables, and if there's a result in my third array ($levenResultsArr) that matches a row in my metaphone_col, then I want the results printed. Somehow, though, I am not referencing the third array correctly in the MySQL statement.
Any advice? Here is part of my PHP code.
$levenResultsArr = array();
foreach ($search_exploded as $search_each => $searchWord) {
$search_each2 = metaphone($searchWord);
echo $search_each2 . "<br/>";
foreach ($metaphoneArr as $metaword => $val) {
$lev = levenshtein($search_each2, $val);
if ($lev < 2) {
array_push($levenResultsArr, $search_each2);
}
}
}
// And shown below is the MySQL statement
$constructs = "
SELECT vt.idvideolist,
vt.videotitle,
vt.videodescription
FROM videolist_tbl vt
INNER JOIN keyword__video k2v ON (vt.idvideolist = k2v.video_id)
INNER JOIN keywords_tbl k ON (k2v.keyword_id = k.idkeywords_tbl)
WHERE k.metaphone_col = '$search_each2'
";
It's only searching using the last word in the array instead of all words in the array.
You're correct that you aren't referencing your array correctly in your query. You are simply referencing the variable '$search_each2'. You want to check the entire array. The best way to do this would to be to convert the array to a string using implode and using the MySQL IN clause. We need to modify the array first to format it correctly:
foreach($levenResultsArr as &$foo){
$foo = "'".$foo."'"; //add single quotes around each object in the array
}
$levenAsStr = implode(",", $levenResultsArr);
Then simply change your last line to the following:
WHERE k.metaphone_col IN (".$levenAsStr.")";
Did this from memory because I'm not in a testing environment, please let me know if there are any syntax errors. Should work for you!
Without seeing more of the code its a bit difficult to determine what is going on. A couple of thoughts though.
What var is the array containing all search terms?
I noticed you are pushing items into $levenResultsArr. I don't see it being used in the query though.
If it is $search_each_2 you may try using the IN syntax:
WHERE k.metaphone_col IN '$search_each2';
This will only match exact values however. i.e.:
some value does not return if the IN array contains value. The array would have to contain some value
If you need it to match partial searches you may try using LIKE with wildcards: %
WHERE k.metaphone_col LIKE "%searchTerm1%"
OR k.metaphone_col LIKE "%searchTerm2%"
OR k.metaphone_col LIKE "%searchTerm3%"
You could potentially use the implode function to create the sql string from the array: http://php.net/manual/en/function.implode.php
I want to implement shopping cart in php. I am using single cookie to store multiple product id and quantity. Now i want to fetch these values from the cookies.
The data is stored in this format : {Product_id-Quantity}
Like this :
A-2,B-4,C-1,D-3
Now i want to use explode function to get these two values product id and quantity separately.
I do not know how to do this. Can anyone figure out a way to implement this ?
here you go - this saves your cookie-string in a PHP array:
$str = "A-2,B-4,C-1,D-3";
$arr = explode(",", $str);
foreach($arr AS $row)
{
$piece = explode("-", $row);
$cookie[$piece[0]] = $piece[1];
}
var_dump($cookie);
notice: your names and values must not contain , or - because you use them as separators.
I'm very new with PHP/Mysql, but I'm trying to make movie database.
There's a form where people can put in info about the movies, and the send button stores it in my database. Then another web page displays the movie list.
The text input and dropdown selections were easy. What I'm really struggling with is the multiple checkbox part. After hours of struggling I finally learned about the php array and how I can store all the values from my checkboxes using implode. My code looks like this:
$genre = implode( ';' , $_POST['genre'] );
This saves all the selected genres in the database, seperated by ;
However, I need help in displaying this data on my html page the way I want:
First off, I want to retrieve the results in a html list, instead of a;b;c
Second, I want to change a;b;c etc to actual words - for example Horror, Action, Comedy. Can this be done?
Hope someone can help! Thanks!
EDIT:
A friend told me that the best way to handle multiple checkbox values is to store them in a different table (moviegenres) and use mapping. So I rearranged my database like this:
One table called 'movies' that has the columns 'movieID' and 'title', and one table called 'moviegenres' that has the columns 'movieID' and 'moviegenre'.
I can still save the title into 'title' in 'movies', but when I want to add a command for adding genre to the 'moviegenres' table, nothing works...
What is the simplest way to do this?
Do I need to different commands for inserting into two tables, or can I do everything in one command, using one variable?
You can take the data say
$genre = 'a:b:c';
and use
$genreArr = explode(';', $genre);
to get this as an array. where you can get the values like
$genreArr[0] = 'a';
$genreArr[1] = 'b';
then in php page, use this code:
echo '<ul>';
foreach($genreArr as $g)
{
echo '<li>'. $g.'</li>';
}
echo '</ul>';
Yes you can used the explode() function to get an array of database checkbox values like you have fetching from db a;b;c
$values = explode(';', $dbcheckboxes);
After this just display in html. If you want to display actual words then make one array of actual words like
$actual_words = array(a => 'Horror', b => 'Action', c => 'Comedy');
Just compare the above database values with actual words array keys and you will get it.
You can get data explode it and loop it to print those values in html.
$checkbox_values=explode(";","a;b;c");
$map=array("a"=>"Apple","b"=>"banana","c"=>"carrot");
foreach($checkbox_values as $value)
{
echo "<p>"+$map[$value]+"</p>";
}
This would be a solution for your question.But since creating a map variable wont be dynamic, it is better to store the display string as it is to database such as "apple;banana;carrot".
$genre = implode( ';' , $_POST['genre'] );
$array_values = explode(';', $genre);
foreach ($array_values as $values) {
echo $values.'<br>';
}
I'm querying a table in a db using php. one of the fields is a column called "rank" and has data like the following:
none
1-bronze
2-silver
3-gold
...
10-ambassador
11-president
I want to be able to sort the results based on that "rank" column. any results where the field is "none" get excluded, so those don't factor in. As you can already guess, right now the results are coming back like this:
1-bronze
10-ambassador
11-president
2-silver
3-gold
Of course, I would like for it to be sorted so it is like the following:
1-bronze
2-silver
3-gold
...
10-ambassador
11-president
Right now the query is being returned as an object. I've tried different sort options like natsort, sort, array_multisort but haven't got it to work the way I'm sure it can. I would prefer keeping the results in an object form if possible. I'm passing the data on to a view in the next step. although, it's perfectly acceptable to pass the object to the view and then do the work there. so it's not an issue after all. :)
thank you for your help. i'm hoping I'm making sense.
How about using this function to sort. I assume if you are getting an object you should convert object to array then use this
function arraySubSort($array, $subkey, $sort = 'asort')
{
foreach($array as $key => $value)
{
$temp[$key] = strtolower($value[$subkey]);
}
$sort($temp);
foreach($temp as $key => $value)
{
$result[] = $array[$key];
}
return $result;
}
$data = $your_array;
$field = 'ranks';
arraySubSort($data,$field);
It will sort the array with the field you assign. If you are getting multiple records its a good thing to use to sort.
Get the values in an array an sort it in PHP using natsort()
Natsort
This will work -
SELECT alphanumeric, integer FROM sorting_test ORDER BY LENGTH(alphanumeric), alphanumeric
