Question

我正在构建一个小的php文件。我需要选择随机复选框。复选框是动态的，因为它们是从具有某些条件的表中拉出来的。

如果我可以随机选择几个复选框，请告诉我如果我从mysql表中获得100个结果，则需要选择10个随机复选框。

<?php
    $n1=0;
    $rambo = strip_tags(@$_POST["assoocc"]); 
    $r11 = strip_tags(@$_POST["ccdate"]);
    $r12 = strip_tags(@$_POST["rrdate"]);
    $submit = @$_POST["submit22"];
    ?>
    <body><div>
    <form action="selectedcc.php" method="post">
    <center>    <table width="600" border="1" cellpadding="1" cellspacing="1">
        <tr>
            <th colspan="3"> Total cases for QA</th>
            <th colspan="2"><?php
            $ticket=mysql_query("SELECT * FROM us_tickets where (status='Resolved') and (associate='$rambo') and (resolve_date >='$r11') and (resolve_date <='$r12')");

            $m1=mysql_num_rows($ticket);
            echo "$m1"; 
            ?></th>
            <th colspan="2"><select   name="assoocc1"  class="form-control" id="sel1" style="width: 150px;" >
                <?php echo "<option value=$rambo selected>".$rambo."</option>";
                ?>
            </select></th>
           <th colspan="1"><input type="submit" name="sub" value="Submit For QA "/></th>

从Generating UNIQUE Random Numbers within a range - PHP

获取随机函数 UniqueRandomNumbersWithinRange

<?php

function UniqueRandomNumbersWithinRange($min, $max, $quantity) {
    $numbers = range($min, $max);
    shuffle($numbers);
    $arr  = array_slice($numbers, 0, $quantity);
    sort($arr);
    return $arr;
}

$chkArr = array();
$rand = UniqueRandomNumbersWithinRange(0, 100, 10);
$rIdx = 0;

for($k=0; $k<100; $k++){
    $caseid1 = $task1 = $asin1 = $sla1 = $associate1 = $quer = "";
    ${"caseid".$k}=mysql_result($ticket,$k, "case_id");
    ${"task".$k}=mysql_result($ticket,$k, "sub_issue");
    ${"asin".$k}=mysql_result($ticket,$k, "asin");
    ${"vendor_credit".$k}=mysql_result($ticket,$k, "vendor_credit");
    ${"create_date".$k}=mysql_result($ticket,$k, "create_date");
    ${"resolve_date".$k}=mysql_result($ticket,$k, "resolve_date");
    ${"root_cause".$k}=mysql_result($ticket,$k, "root_cause");
    ${"associate".$k}=mysql_result($ticket,$k, "associate");

    $chk = '';
    if( in_array($k, $rand) )
        $chk = "checked";

    array_push($chkArr, "<tr>"."<th>"."<input type='checkbox' ".$chk ." value='${'caseid'.$k}' name='checkboxvar[]'>"."</th>"."<th>".${'caseid'.$k}."</th>"."<th>".${'task'.$k}."</th>"."<th>".${'asin'.$k}."</th>"."<th>".${'vendor_credit'.$k}."</th>"."<th>".${'create_date'.$k}."</th>"."<th>".${'resolve_date'.$k}."</th>"."<th>".${'root_cause'.$k}."</th>"."</tr>");
}
echo implode($chkArr);

?>
