Question

我试图在php中放入两个if语句，但只执行其中一个

        <?php
        if (isset($_POST["redeembutton"])) {
            $redeemedBalance = strip_tags($_POST["vidcoinamount"]);
            $actualBalance = get_balance();

                if ($actualBalance < $redeemedBalance && $redeemedBalance < 500) { // If trying to redeem what the user don't have OPEN ?>
                <span class='greeting'>Sorry, you can't exchange that...</span><br/>
                <span class='heading'>You have <?php echo $row['balance']; ?> Beezes that you can exchange here.</span><br/>
                <span class='heading'>Enter the amount you wish to redeem and hit submit.</span><br/>
                <form class="btcregform" action='redeem.php' method='post'>
                    <input class="btcregforminput" type='text' value='' id='vidcoinamount' name='vidcoinamount'>
                    <input class="btcregformbutton" type='submit' value='Submit'                   id='button' name='redeembutton'>
                </form>
                <?php // If trying to redeem what the user don't have CLOSE
                } else { ?>  
                <?php
                    // Redeem amount is OK OPEN
                    $walletID = get_wallet_id();
                    $date = date("Y-m-d H:i:s");
                    $ipadr = $_SERVER['REMOTE_ADDR'];
                    $iscomplete = 'No';
                    $deductamount = $actualBalance-$redeemedBalance;
                    // Get current BTC price from BlockChain into $btcprice (0,01 usd is virool payment per video) 
                    $btcprice = 0.00004335;
                    // Multiply the redeemed balance with the amount in actual BTC worth 0,01 usd.
                    $valueInBTC = $btcprice * $btcprice;
                    // This gets rid of some formatting issues
                    $actualBTC = sprintf("%.10f",$valueInBTC);
                    $setBalance = " UPDATE users SET balance='$deductamount' WHERE username='$username' ";
                    $con = connect();
                    mysqli_query($con, $setBalance) or die ('Couldn\'t set balance to database !');
                    $setRequest = " INSERT INTO requests VALUES ('','$username','$walletID','$redeemedBalance','$actualBTC','$date','$ipadr','$iscomplete') ";
                    mysqli_query($con, $setRequest) or die ('Couldn\'t set payment request for admin into database !');
                    mysqli_close($con);
                ?>
                <span class='greeting'>Thank you!</span><br/>
                <span class='heading'>Your exchange request has been received.</span><br/>
                <span class='heading'>Please give us up to 48 hours to process it. On weekends it may take longer...</span><br/>
                                <span class='heading'>You have <b><?php print get_balance(); ?></b> Beezes left in your account</span><br/>
                                <br>
<?php
$dollars = get_balance()  / 100;
?>
<?php print get_balance(); ?> Beezes = $<?php print $dollars; ?><br>
                <?php } //If redeem amount is OK CLOSE ?>
        <?php } else { // If the user hasn't done anything yet OPEN ?>
        <span class='greeting'>Redeem your Beezes</span><br/>
        <span class='heading'>Enter the amount you wish to redeem and hit submit.</span><br/>
        <form class="btcregform" action='redeem.php' method='post'>
            <input class="btcregforminput" type='text' value='' id='vidcoinamount' name='vidcoinamount'><br><br>
            <input class="btcregformbutton" type='submit' value='Submit' id='button' name='redeembutton'>
        </form>
        <?php } //If the user hasn't done anything yet CLOSE ?>

我的问题是那部分

if ($actualBalance < $redeemedBalance && $redeemedBalance < 499)

如果实际余额大于兑换余额，那么它的工作原理，但是如果兑换保险金额小于500的部分没有被执行，那么它的行为就像它甚至不存在一样。请帮忙（新手在这里）

说实话，我对问题有所了解，但也许这会有所帮助：

<?php

$balance = 1500;
$price = 500;

 if ($balance >= $price) {  echo "There You go...."; }
 else {  echo "Sorry, You cant..."; } 


?>
