使用SQL和PHP进行多个INSERT / UPDATE

Question

can you suggest me the best solution to make multiple INSERT and UPDATE at the same time, please?

I use a SELECT to retrieve records from a table and I let the user to update the content of each record if he checks the checkbox "insert". At the moment, I use a form button for each set of records.

Since there can be lots of records, I would like to use only a single "form" and a single "form button" for all the data and to update or insert only the set of records when the user checks the checkbox. Is it possible? If yes, how? Can you give me any suggestions, please?

$sql = "select * from table1 where nome_area like '%$nome_area%' AND nome_voce like '%$nome_voce%'";

    $rs = mysql_query( $sql ) or die('Database Error: ' . mysql_error());
    $num = mysql_num_rows( $rs );

    if($num >= 1 ){         

        echo "<table align=\"center\" cellspacing=0 cellpadding=100>";

        echo "<tbody><tr><td width=\"20%\">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;</td><td>";

        while($row = mysql_fetch_array( $rs )){

            echo "<form name=\"form\" id=\"form\" action=\"update.php\" method=\"post\">";
        echo "<table data-role=\"table\" class=\"ui-responsive\"  cellspacing=\"20\" ";
        echo "<tbody>";

            echo "<tr>";
            echo "<td>";
            echo "<font text color=\"red\">Insert</font> &nbsp;&nbsp;&nbsp;</td><td><input type=\"checkbox\"  name=\"insert\" value=\"1\" id=\"insert\"></td></tr>";
            echo "<tr><td><b>Tipo Area</b>:</td><td>".$row['nome_area']. " </td></tr><tr><td><b>Nome della voce</b>: </td><td> " .$row['nome_voce'] . "</td></tr>";
echo "<tr><td>";
            echo "<input type=\"hidden\" style=\"width:0; height:0; border:0; background-color:inherit; overflow:hidden;\" name=\"id_voce\"  maxlength=\"50\" value=\"" . $row['ID'] . "\">";
            echo "<input type=\"hidden\" style=\"width:0; height:0; border:0; background-color:inherit; overflow:hidden;\" name=\"nome_azienda\"  maxlength=\"50\" value=\"" .$name. "\">"; // azienda
            echo "<input type=\"hidden\" style=\"width:0; height:0; border:0; background-color:inherit; overflow:hidden;\" name=\"nome_area\"  maxlength=\"50\" value=\"" .$row['nome_area']. "\">";
            echo "<input type=\"hidden\" style=\"width:0; height:0; border:0; background-color:inherit; overflow:hidden;\" name=\"nome_voce\"  maxlength=\"50\" value=\"" .$row['nome_voce']. "\">";
            echo "</td></tr>";
            echo "<tr><td colspan=\"2\"> <input type=\"submit\" value=\"Associa la voce di contratto all'azienda\" id=\"search-btn\" style=\"height:50px; \"; /></td></tr>";
            echo "</tbody></table>";
                echo "</form>";



}

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

    }else{
        // if no records found
        echo "<br><br><b>Nessun risultato trovato!</b></div>";
    }

In my update.php page, I just read the form values and INSERT them into my table:

.....
mysql_query("INSERT INTO table2 (id_voce,associazione, nome_azienda, nome_area, nome_voce, created_date) VALUES('$id_voce','$associa','$nome_azienda','$nome_area','$nome_voce','$time')");

One way would be to generate a sequential row id # for each row. Let's assume this is your collection of rows from the database:

$rs = array(
    array('ID'=>'111', 'nome_area'=>'first nome area',  'nome_voce'=>'first nome voce'),
    array('ID'=>'222', 'nome_area'=>'second nome area', 'nome_voce'=>'second nome voce'),
    array('ID'=>'333', 'nome_area'=>'third nome area',  'nome_voce'=>'third nome voce'),
);

Now create the table with a checkbox that has a sequential ID number:

$rowcounter = 0;
foreach ($rs as $row) {
    $rowcounter++;
    echo <<<HERE
<tr>
  <td><input type="checkbox" name="row_{$rowcounter}_checkbox" value="1" /></td>
  <td>
    ID: {$row['ID']}
    <input type="hidden" name="row_{$rowcounter}_ID" value="{$row['ID']}" />
  </td>
  <td>
    Tipo Area: {$row['nome_area']}
    <input type="hidden" name="row_{$rowcounter}_nome_area" value="{$row['nome_area']}" />
  </td>
  <td>
    Nome della voce: {$row['nome_voce']} 
    <input type="hidden" name="row_{$rowcounter}_nome_voce" value="{$row['nome_voce']}" />
  </td>
</tr>

HERE;
}

When the form is submitted, you can find all checkboxes that are checked, then process the other form values related to that unique row ID:

foreach ($_POST as $key=>$val) {
    if (preg_match("/^row_(\d+)_checkbox$/",$key,$matches) && $val == "1") {

        $rowid = $matches[1];

        $ID = $_POST["row_{$rowid}_ID"];
        $nome_area = $_POST["row_{$rowid}_nome_area"];
        $nome_voce = $_POST["row_{$rowid}_nome_voce"];

        print "The checkbox was checked for the row with this data:\n";
        print "ID: $ID\n";
        print "nome_area: $nome_area\n";
        print "nome_voce: $nome_voce\n";
    }
}

EDIT For your own HTML code, it would be something like this:

$rowcounter = 0;
echo "<form name=\"form\" id=\"form\" action=\"update.php\" method=\"post\">";
echo "<table data-role=\"table\" class=\"ui-responsive\"  cellspacing=\"20\" ";
echo "<tbody>";
while($row = mysql_fetch_array( $rs )){
    $rowcounter++;
    echo "<tr>";
    echo "<td>";
    echo "<font text color=\"red\">Insert</font> &nbsp;&nbsp;&nbsp;</td><td><input type=\"checkbox\"  name=\"row_{$rowcounter}_insert\" value=\"1\" id=\"insert\"></td></tr>";
    echo "<tr><td><b>Tipo Area</b>:</td><td>".$row['nome_area']. " </td></tr><tr><td><b>Nome della voce</b>: </td><td> " .$row['nome_voce'] . "</td></tr>";
    echo "<tr><td>";
    echo "<input type=\"hidden\" style=\"width:0; height:0; border:0; background-color:inherit; overflow:hidden;\" name=\"row_{$rowcounter}_id_voce\"  maxlength=\"50\" value=\"" . $row['ID'] . "\">";
    echo "<input type=\"hidden\" style=\"width:0; height:0; border:0; background-color:inherit; overflow:hidden;\" name=\"row_{$rowcounter}_nome_azienda\"  maxlength=\"50\" value=\"" .$name. "\">"; // azienda
    echo "<input type=\"hidden\" style=\"width:0; height:0; border:0; background-color:inherit; overflow:hidden;\" name=\"row_{$rowcounter}_nome_area\"  maxlength=\"50\" value=\"" .$row['nome_area']. "\">";
    echo "<input type=\"hidden\" style=\"width:0; height:0; border:0; background-color:inherit; overflow:hidden;\" name=\"row_{$rowcounter}_nome_voce\"  maxlength=\"50\" value=\"" .$row['nome_voce']. "\">";
    echo "</td></tr>";
}
echo "<tr><td colspan=\"2\"> <input type=\"submit\" value=\"Associa la voce di contratto all'azienda\" id=\"search-btn\" style=\"height:50px; \"; /></td></tr>";
echo "</tbody></table>";
echo "</form>";

and a form processor something like this:

foreach ($_POST as $key=>$val) {
    if (preg_match("/^row_(\d+)_insert$/",$key,$matches)) {
        $rowid = $matches[1];
        $nome_id_voce = $_POST["row_{$rowid}_nome_id_voce"];
        $nome_area    = $_POST["row_{$rowid}_nome_area"];
        $nome_voce    = $_POST["row_{$rowid}_nome_voce"];
    }
}

使用ON DUPLICATE KEY UPDATE语法执行新记录的插入或现有记录的更新（基于PK）

Answer 3

You need adding record id to element name. Example:

echo "<input type=\"hidden\" style=\"width:0; height:0; border:0; background-color:inherit; overflow:hidden;\" name=\"nome_voce_". $row['ID'] ."\"  maxlength=\"50\" value=\"" .$row['nome_voce']. "\">";

You can get all variables in update.php and prepare multiple insert command. Also there are js based table editor, you can use them. Easy one: http://codepen.io/ashblue/pen/mCtuA
