To create a drop-down filter for an HTML table based on a SELECT query in MySQL, you can use JavaScript to dynamically update the query's WHERE clause and retrieve the filtered results from the database. Here is an example of how you might do this:
In your HTML file, create a SELECT element that lists the skill categories from the tc_skill_categories table:
<select id="skill-filter">
<option value="">All Skills</option>
<option value="Roofing">Roofing</option>
<!-- Add options for each skill category in tc_skill_categories -->
</select>
Use JavaScript to listen for changes to the SELECT element and update the WHERE clause of the SELECT query for the HTML table:
const skillFilter = document.getElementById("skill-filter");
skillFilter.addEventListener("change", function() {
const selectedSkill = this.value;
let query = "SELECT * FROM tc_skill_assessments WHERE 1=1";
if (selectedSkill) {
query += ` AND skill_id IN (SELECT skill_id FROM tc_skill_categories WHERE skill = ${selectedSkill})`;
}
executeQuery(query);
});
Write a function to execute the SELECT query and update the HTML table with the results. This function will likely involve using an API or library to send the query to the MySQL database and retrieve the results, as well as updating the HTML table with the returned data.
Note that this is just one way to implement a drop-down filter for an HTML table using a MySQL SELECT query. There are many other approaches you could take, and the specific details will depend on your specific needs and environment.
