PHP Search Data By Date

[CaptainNek]

Okay, i will try to make it short.
I want to search data by date using PHP ONLY, can anyone paste their related source code here please?

Maybe a bit too short? What kind of data are you sorting? (If it's a database, the SQL you use can do that easily if the relevant table is properly defined. If it's a CSV or JSON file, that's a whole different story.)

Yes i'm fetching the data from database. I have a form created for user to input a date range for searching data, so my query is like this;

if(isset($_POST['btnDateSearch'])){
$dateValue=$_POST['dateValue'];
$query="SELECT * FROM tb_expenses where date='$dateValue'";
$dateConnect=mysqli_query($connect,$query);

I DON'T KNOW WHAT TO DO NEXT FROM HERE!!

I'd start by making sure you get a usable date from the form, while avoiding SQL injection attacks:

if(isset($_POST['dateValue'])) {
  $date = strtotime($_POST['dateValue']);
  if(!$date) {
    // handle error of invalid date here
  }
  else {
    $dateValue = date('Y-m-d', $date);
    // now do your query
  }
}

As opposed to what's next, that depends on what you want to do with what gets retrieved from the DB. mysqli_query() will return false if it fails to run, so you should check for that first and deal with any errors. Otherwise it should return a mysqli_result object (see https://www.php.net/manual/en/class.mysqli-result.php), which you could then use in a foreach() loop on the results of a mysqli_fetch_all(), or a while() loop on mysqli_fetch_assoc(), or whatever you prefer to do, outputting the results as desired (an HTML table row?).

Okay i already have a code to fetch all data as history data:
<tr>
<?php

                        $qury = "SELECT * FROM expenses;";
                        $ret = mysqli_query($connect, $qury);
                        while($row = mysqli_fetch_assoc($ret)){?>

                        <th scope="row"><?php echo $row['id']; ?></th>
                        <td> <?php echo $row['item']; ?> </td>
                        <td> <?php echo $row['date'];?> </td>
                        <td>  <?php  echo $row['paymentType']; ?> </td>
                        <td><?php echo $row['amount']; ?> </td>
                        <td>

How do i do the date search without interrupting the history table? should i have another html table or it's still going to be in the same table tag??

What is the difference between the expenses and tb_expenses table? Is there a field in one or the other that relates entries to the other table? If so, is it a one-to-one, many-to-one, or many-to-many relationship? Depending on those relationships and what is it functionally that you are ultimately trying to do, there may be a way to do a single query against both tables, using some sort of SQL join between the two tables.

[CaptainNek]

I made a mistake at the first post, its the same table "expenses" not "tb_expenses"

[NogDog]

That would be the general pattern. I might first do a mysqli_num_rows() check to handle any case where you get zero rows returned. Assuming it's >= 1, then the basic idea would be to output your table tag and probably a <tr>...</tr> line with <th>...</th> elements for the table column headers, then do your while() loop, including <tr> and </tr> tags wrapping up the rows, e.g.:

while($row = mysqli_fetch_assoc($ret)) {
  echo "<tr>";
  foreach(array('col_1', 'col_2', 'etc') as $key) { // replace actual column names in array
    echo "<td>".htmlspecialchars($row[$key])."</td>";
  }
  echo "</tr>\n";
}

Then stick your closing </table> tag after the end of the loop.
