我如何将数据表用于 Php While 循环

Question

How can i show Select statement results in the Data-table in PHP. I have used the following code to display record from Mysql table but not working.

I have tried this but no luck

Select Statement

$sql = "SELECT demand.itemid,demand.qty, MIITEM.descr,MIITEM.descr,supplier.suplId,supplier.suplProdCode,supplier.itemId,MIILOC.qStk,MIILOC.qWIP,MIILOC.qRes, MIILOC.qOrd
FROM MIITEM
LEFT JOIN demand
ON MIITEM.itemId=demand.itemId
LEFT OUTER JOIN supplier
ON MIITEM.itemId = supplier.itemId
LEFT OUTER JOIN MIILOC
ON MIITEM.itemId = MIILOC.itemId
WHERE MIITEM.itemId=demand.itemId AND supplier.itemId=demand.itemId";

$result = $conn->query($sql);

Displaying Records

echo"<table id='example' class='display' cellspacing='0' width='100%'>
    <thead>
      <tr style='background:#ccc;'>
<th STYLE='WIDTH:50px; padding:7px'>ID</th>
<th STYLE='WIDTH:250px; padding:7px'>Description</th>

<th STYLE='WIDTH:100px; padding:7px'>Supplier#</th>
<th STYLE='WIDTH:200px; padding:7px'>Supplier </th>
<th STYLE='WIDTH:100px; padding:7px'>ON WO</th>
<th STYLE='WIDTH:100px; padding:7px'>Stock</th>
<th STYLE='WIDTH:100px; padding:7px'>WIP</th>
<th STYLE='WIDTH:100px; padding:7px'>Reserve</th>
<th STYLE='WIDTH:100px; padding:7px'>On Order</th>

</tr>   </thead></table>";
if ($result->num_rows > 0) {

    while($row = $result->fetch_assoc()) {
      echo"<table id='example' class='display' cellspacing='0' width='100%'><tbody>
<tr>
 <th STYLE='WIDTH:50px; padding:7px'>"; echo$row["itemid"];echo"</th>
 <th STYLE='WIDTH:250px; padding:7px'>"; echo$row["descr"];echo"</th>
 <th STYLE='WIDTH:100px; padding:7px'>"; echo$row["suplId"];echo"</th>
 <th STYLE='WIDTH:200px; padding:7px'>"; echo$row["suplProdCode"];echo"    </th>";
echo"<th STYLE='WIDTH:100px; padding:7px'>";echo$row["qty"];echo"</th>";
echo"<th STYLE='WIDTH:100px; padding:7px'>";echo$row["qStk"];echo"</th>";
echo"<th STYLE='WIDTH:100px; padding:7px'>";echo$row["qWIP"];echo"</th>";

echo"<th STYLE='WIDTH:100px; padding:7px'>";echo$row["qRes"];echo"</th>";

echo"<th STYLE='WIDTH:100px; padding:7px'>";echo$row["qOrd"];echo"</th>";


echo"</tr></tbody></table>";

Here is the Javascript code and the CSS file from CDN but nothing is changing.

<script type="text/javascript" src="//code.jquery.com/jquery-1.12.3.min.js"></script>

<script type="text/javascript" src="https://cdn.datatables.net/select/1.2.0/js/dataTables.select.min.js"></script>


  <script type="text/javascript">
$(document).ready(function() {
    $('#example').DataTable( {
        select: true
    } );
} );

  </script>

Your markup was very odd, it looked like you were inserting duplicate tables, with the same ID, for each $row . Did anything go into the UI at all? It's always worthwhile to check both the source of the page and also the validity of the markup using an online HTML Validity checker. From what I understand of your needs I've created this snippet :

if ($result->num_rows > 0) {
    echo "
        <style>
            th, td {
                width: 100px;
                padding: 7px;
            }
            .fifty {
                width: 50px;
            }
            .twohundred {
                width: 200px;
            }
            .twohundredfifty {
                width: 250px;
            }
        </style>
        <table id='example' class='display' cellspacing='0' width='100%'>
            <thead>
                <tr style='background:#ccc;'>
                    <th class='fifty'>ID</th>
                    <th class='twohundredfifty'>Description</th>
                    <th>Supplier#</th>
                    <th class='twohundred'>Supplier </th>
                    <th>ON WO</th>
                    <th>Stock</th>
                    <th>WIP</th>
                    <th>Reserve</th>
                    <th>On Order</th>
                </tr>   
            </thead>
            <tbody>
    ";
    while($row = $result->fetch_assoc()) {
        echo "<tr>";
        echo "    <td class='fifty'>".$row["itemid"]."</td>";
        echo "    <td class='twohundredfifty'>".$row["descr"]."</td>";
        echo "    <td>".$row["suplId"]."</td>";
        echo "    <td class='twohundred'>".$row["suplProdCode"]."</td>";
        echo "    <td>".$row["qty"]."</td>";
        echo "    <td>".$row["qStk"]."</td>";
        echo "    <td>".$row["qWIP"]."</td>";
        echo "    <td>".$row["qRes"]."</td>";
        echo "    <td>".$row["qOrd"]."</td>";
        echo "</tr>";
    }
    echo "
            </tbody>
        </table>
    ";
}

It's also always a really good idea to check your code using indents so that you can ensure that the flow of the markup is correct.

Hope that helps.

Please try this code

<?php
//you dont need where condition Left join already filter data over all of your tables demand,supplier, MIILOC
$sql = "SELECT demand.itemid,demand.qty, MIITEM.descr,MIITEM.descr,supplier.suplId,supplier.suplProdCode,supplier.itemId,MIILOC.qStk,MIILOC.qWIP,MIILOC.qRes, MIILOC.qOrd
FROM MIITEM
LEFT JOIN demand
ON MIITEM.itemId=demand.itemId
LEFT OUTER JOIN supplier
ON MIITEM.itemId = supplier.itemId
LEFT OUTER JOIN MIILOC
ON MIITEM.itemId = MIILOC.itemId";

$result = $conn->query($sql);
if (!$result) {
 printf("Errormessage: %s\n", $mysqli->error);
 die;
}

$table = "<table id='example' class='display' cellspacing='0' width='100%'>
<thead>
  <tr style='background:#ccc;'>
    <th STYLE='WIDTH:50px; padding:7px'>ID</th>
    <th STYLE='WIDTH:250px; padding:7px'>Description</th>

    <th STYLE='WIDTH:100px; padding:7px'>Supplier#</th>
    <th STYLE='WIDTH:200px; padding:7px'>Supplier </th>
    <th STYLE='WIDTH:100px; padding:7px'>ON WO</th>
    <th STYLE='WIDTH:100px; padding:7px'>Stock</th>
    <th STYLE='WIDTH:100px; padding:7px'>WIP</th>
    <th STYLE='WIDTH:100px; padding:7px'>Reserve</th>
    <th STYLE='WIDTH:100px; padding:7px'>On Order</th>
</tr>   </thead>";

if ($result->num_rows > 0) {
    $table .= "<tbody>";
    while($row = $result->fetch_assoc()) {
      $table .= "
      <tr>
        <th STYLE='WIDTH:50px; padding:7px'>{$row["itemid"]}</th>
        <th STYLE='WIDTH:250px; padding:7px'>{$row["descr"]}</th>
        <th STYLE='WIDTH:100px; padding:7px'>{$row["suplId"]}</th>
        <th STYLE='WIDTH:200px; padding:7px'>{$row["suplProdCode"]}</th>
        <th STYLE='WIDTH:100px; padding:7px'>{$row["qty"]}</th>
        <th STYLE='WIDTH:100px; padding:7px'>{$row["qStk"]}</th>
        <th STYLE='WIDTH:100px; padding:7px'>{$row["qWIP"]}</th>
        <th STYLE='WIDTH:100px; padding:7px'>{$row["qRes"]}</th>
        <th STYLE='WIDTH:100px; padding:7px'>{$row["qOrd"]}</th>
    </tr>";
}
$table .= "</tbody>"
}
$table .= "</table>";

echo $table;
