Search All items from select box in php code - php

Question

I have form and php file, and I need to query color in array data from database.
data looks like
red,white mustang 1977
black,blue ford 2000
white,pink,blue opel 2003
and form looks like
<form method="POST" action="select.php">
<p><input type="radio" value="just" checked name="selection">just selected<input type="radio" name="selection" value="allinclude">all include </p>
<p><input type="checkbox" name="color[]" value="ON">red</p>
<p><input type="checkbox" name="color[]" value="ON">blue</p>
<p><input type="checkbox" name="color[]" value="ON">black</p>
<p><input type="checkbox" name="color[]" value="ON">white</p>
<p><input type="checkbox" name="color[]" value="ON">pink</p>
<p> </p>
<p><input type="submit" value="Submit" name="B1"><input type="reset" value="Reset" name="B2"></p>
</form>
and I need 2 sql query, one of check all selected options together in data, and one of any of them in data
in my select.php
$selection= $_POST["selection"];
$color=implode(",",$_POST["color"]);
$sql= mysql_query("select model,year,color where color like '%".$color."%'");
When I select blue and white, sql returns no row.
If I select white, then returns 2 row
But I want to select all include radio box and select blue and white then return 3 rows
How can I write second sql for all included selection?
Here is new codes, but this is only query latest item in array, not all selected for 'just' section of selection form
$selection= $_POST["selection"];
$color=implode(",",$_POST["color"]);
if($selection=='just'){
$colorselect = explode(',', $color);
foreach($colorselect as $b)
{
$mycolor = trim($b);
$sql= mysql_query("select model,year,color where color like '%".$mycolor."%'");
}
}
else{
$sql= mysql_query("select model,year,color where color like '%".$color."%'");
}

Answer 1

If I understand your problem correctly, your first query gets all rows that include all of the colors selected - and you need a second query that will get all rows that include just one or more of the colors selected. In that case, you need your query to include a series of ORs that will check for each individual color in each row. (Note: your query seems to be missing a FROM statement. I have added this in, assuming your table is called cars).
Assuming $colors is an array of selected colors, eg: ['blue', 'white', 'red'], you could set up your query as follows:
$query = 'SELECT model,year,color FROM cars WHERE ';
$or = '';
foreach ($colors as $color) {
$query .= $or . "color LIKE '%" . $color . "%'";
$or = ' OR ';
}
This will effectively build a query that looks like this:
SELECT model,year,color
FROM cars
WHERE color LIKE '%blue%'
OR color LIKE '%white%'
OR color LIKE '%red%'
which will select all the rows from your example data - each row contains at least one of the colors selected. If you wanted to change this logic to get all rows that include all of the colors, simply change OR to AND - this will match rows that have all selected colors, regardless of the order in which they were selected.
Additional thoughts:
Storing comma separated values like blue,white is usually bad practice. Consider normalizing your data and use a system that includes something like a colors and car_colors table.
mysql_* functions are deprecated. Consider switching to mysqli_* or pdo
UPDATE:
Here is the complete system. This will create the appropriate query based on which radio button is selected:
(Assuming the sample data you provided is in a table called cars)
form:
<form method="POST" action="select.php">
<p><input type="radio" value="just" checked name="selection">just selected<input type="radio" name="selection" value="allinclude">all include </p>
<p><input type="checkbox" name="color[]" value="red">red</p>
<p><input type="checkbox" name="color[]" value="blue">blue</p>
<p><input type="checkbox" name="color[]" value="black">black</p>
<p><input type="checkbox" name="color[]" value="white">white</p>
<p><input type="checkbox" name="color[]" value="pink">pink</p>
<p> </p>
<p><input type="submit" value="Submit" name="B1"><input type="reset" value="Reset" name="B2"></p>
</form>
select.php:
$selection = $_POST['selection'];
$colors = $_POST['color'];
$op = $selection == 'just' ? ' AND ' : ' OR ';
$query = 'SELECT model,year,color FROM cars WHERE ';
$and_or = '';
foreach ($colors as $color) {
$query .= $and_or . "color LIKE '%" . $color . "%'";
$and_or = $op;
}
$sql = mysql_query($query);

The effective HTML of Fred -ii-s comment is:
<form method="POST" action="select.php">
<p><input type="radio" value="just" checked name="selection">just selected<input type="radio" name="selection" value="allinclude">all include </p>
<p><input type="checkbox" name="colors[]" value="red">red</p>
<p><input type="checkbox" name="colors[]" value="blue">blue</p>
<p><input type="checkbox" name="colors[]" value="black">black</p>
<p><input type="checkbox" name="colors[]" value="white">white</p>
<p><input type="checkbox" name="colors[]" value="pink">pink</p>
<p> </p>
<p><input type="submit" value="Submit" name="B1"><input type="reset" value="Reset" name="B2"></p>
</form>
And then in your PHP code you would just use the $_POST['colors'] array of data like any other array in PHP.
$colors = implode($_POST['colors'],',');
$sql= mysql_query("select model,year,color where color in (".$colors.")");

Your HTML:
<form method="POST" action="select.php">
<p><input type="radio" value="just" checked name="selection">just selected<input type="radio" name="selection" value="allinclude">all include </p>
<p><input type="checkbox" name="color[]" value="red">red</p>
<p><input type="checkbox" name="color[]" value="blue">blue</p>
<p><input type="checkbox" name="color[]" value="black">black</p>
<p><input type="checkbox" name="color[]" value="white">white</p>
<p><input type="checkbox" name="color[]" value="pink">pink</p>
<p> </p>
<p><input type="submit" value="Submit" name="B1"><input type="reset" value="Reset" name="B2"></p>
</form>
Your PHP:
$colors = array("red", "blue", "black", "white", "pink");
// Make sure that only allowed colors make through - we don't want SQL injection
$selection = array();
foreach ($_POST["colors"] as $color)
{
if (in_array($color, $colors) === true)
{
$selection[] = $color;
}
}
// Now a bit of magic
$sql= mysql_query("select model,year,color from data where color like '%" . implode("%' " . ($_POST["selection"] === "just" ? "or" : "and") . " color like '%",$selection) . "%'");
